How to Activate the iPhone Debug Console or Web Inspector

Use Safari's web developer tools to study problematic websites

• Saint Mary-of-the-Woods College
• Switching from Android

What to Know

• Activate Web Inspector on iOS: Go to Settings > Safari > Advanced and move the Web Inspector toggle switch to the On position.
• Use Web Inspector on macOS: Connect your iOS device to a Mac and choose the URL to inspect from the Develop menu.

If you run into a bug or another issue with a website on Safari mobile, use the Web Inspector tool to investigate. This article explains how to use the Safari console for iPhone to debug errors with the help of your Mac computer. Instructions apply to iPhones with iOS 14, iOS 12, or iOS 11, and well as Macs with macOS Big Sur (11.0), macOS Catalina (10.15), or macOS Mojave (10.14).

Activate Web Inspector on Your iPhone or Other iOS Device

The Web Inspector is disabled by default since most iPhone users have no use for it. However, if you're a developer or you're curious, you can activate it in a few short steps. Here's how:

Open the iPhone  Settings  menu.

On an iPhone with an early version of iOS, access the Debug Console through Settings > Safari > Developer > Debug Console . When Safari on the iPhone detects CSS, HTML, and JavaScript errors, details of each display in the debugger.

Scroll down and tap  Safari  to open the screen that contains everything related to the Safari web browser on your iPhone, iPad, or iPod touch.

Scroll to the bottom of the page and select Advanced .

Move the Web Inspector toggle switch to the On position.

Connect Your iOS Device to Safari on a Mac

To use the Web Inspector, connect your iPhone or another iOS device to a Mac that has the Safari web browser and enable the Develop menu .

With Safari open, select Safari from the menu bar and choose  Preferences .

Select the  Advanced  tab.

Select the Show Develop menu in menu bar check box and close the settings window.

From the Safari menu bar, select Develop and choose the name of your attached iOS device, then select the URL that appears under Safari to open the debug console for that site.

After you connect your device, use your Mac to inspect the website you want to debug and have it open in the Safari mobile browser.

What Is Web Inspector?

Web developers use Web Inspector to modify, debug, and optimize websites on Macs and iOS devices. With Web Inspector open, developers can inspect the resources on a web page. The Web Inspector window contains editable HTML and notes regarding the styles and layers of the web page in a separate panel.

Before iOS 6, the iPhone Safari web browser had a built-in Debug Console that developers used to find web page defects. Recent versions of iOS use Web Inspector instead.

With Safari 9 and OS X Mavericks (10.9), Apple introduced Responsive Design Mode in Web Inspector. Developers use this built-in simulator to preview how web pages scale to different screen sizes, resolutions, and orientations.

To set up Web Inspector on your iPad, open your iPad's Settings and select Safari > Advanced , then turn Web Inspector On . Connect the iPad to a Mac computer, then open Safari on the Mac and select Safari > Preferences > Advanced , then turn on Show Develop menu in menu bar .

You cannot just connect your iPhone to a Windows PC and start using Web Inspector through Chrome like you can with a Mac. Installing package manager software can provide you a sort of workaround, but it's not recommended unless you're familiar with the package management app you intend to use.

Inspecting Safari’s Web Browser on a Mobile Device

Article summary

Why inspect on a device mobile browser, set up osx safari for inspection.

Inspecting the browser gives you access to the details of a website or application. Using built-in developer tools and third-party add-ons, we can view the inner workings of an application.

For example, you can see the content structure in DOM, view the console for logs or error messages, and review network requests for assets being loaded. When debugging a user interface problem, you can use the elements panel to modify live content on the screen, changing the content, type color, or button sizes.

By parsing though this information, you can often get to the bottom of your issue.

Most browsers now have tools to mimic devices such as tablets and mobiles, so you can inspect and debug right on your computer. This has been extremely helpful in developing and testing our work, but sometimes, it doesn’t go far enough.

Because this solution is just emulating a mobile device, it doesn’t always have the same oddities as the actual device. Fortunately, you can plug in a device and inspect it just as you would with a normal browser on your computer.

Let’s walk through an example using Safari.

For this solution to work, both your device and computer need to be properly configured. In our example, we’ll be using OSX Safari on an iPhone with iOS 10 and a Macbook Pro.

Set up your device

• Click Setting to access your general iPhone Settings.
• Scroll and select Safari’s Settings.
• Scroll and select Advanced.
• Toggle the Web Inspector to On.

Set up your computer

• Open Safari.
• Open Preferences from the File Safari dropdown menu.
• Click the Advance tab in the options.
• Turn on Show Develop menu in menu bar.

Great! We’re almost there.

Now plug your device into the computer via USB. Using the mobile device, navigate to a page or application you want to inspect.

Next, shift over to your computer. With Safari open, select the Develop menu in the menu bar. Toward the top of that list, you should see your device’s name and the windows that are available to inspect. Select the page or application to inspect, and the inspection window will open.

From here, the review process works the same as it would if you were inspecting a window on your local machine. There are a couple of drawbacks such as not being able to target an element with your mouse or right-click to inspect an element. Instead, you’ll have to navigate up and down the DOM tree or leverage the find feature via Command + F in the inspect window.

This method has allowed us to fix difficult bugs as well as test and prototype right in the native browser. Give it a try next time you’re in that situation.

How can I quickly open a mobile view of a page in a desktop browser?

Since we're now in a mobile-first world, it becomes more and more important to be able to test websites easily on mobile phones, or on emulated mobile phones. I collaborate with people who work on websites and social media offerings, and I would like to encourage them to regularly open websites from their desktop browsers in a mobile view. I'm specifically thinking of the browser's built-in "mobile view" feature, which is often hidden among all the other developer tools a browser provides, but I'm happy to consider anything which is just as quick to set up.

How can you open a mobile view of a website from a desktop browser?

• 24 "Since we're now in a mobile-first world" Woah there a minute... context is for kings. –  Lightness Races in Orbit Commented Feb 6, 2018 at 12:49
• 3 Just a comment - don't know the context really, but if I was asked to be opening webpages from my desktop/laptop in mobile view first ....what's the point of using the desktop? I hope by "encourage", you're not forcing it via some code or other method. Especially since many webpages that do format for mobile are pared down quite a bit and don't have full functionality. –  BruceWayne Commented Feb 6, 2018 at 16:27
• 1 Add a change user agent or similar extension or plug in to your browser, and set a smart phone user agent. –  Salman A Commented Feb 6, 2018 at 17:10
• 1 “I would like to encourage people to regularly open websites from their desktop browsers in a mobile view.” ...That's goofy. And waste all that desktop screen real estate? Desktop and mobile both have their place, and that's why responsive solutions have been developed. Let's deliver the best experience possible for every user, and let people browse on the device that's most comfortable for them. Anyway, valid question, as web designers and developers need to emulate multiple devices when building sites. –  Mentalist Commented Feb 7, 2018 at 2:52
• 2 @Mentalist I meant people who are working on websites and social media offerings. –  Flimm Commented Feb 7, 2018 at 7:28

• In Windows/Linux, press Ctrl + Shift + M
• In macOS, press option + command + M

You can also find the menu item under ("Tools"), "Web Developer", "Responsive Design Mode".

Chrome and Edge:

You need to have "Developer Tools" open first:

• In Windows/Linux, press Ctrl + Shift + I or just F12
• In macOS, press option + command + I

Once developer tools is open and focused, you can toggle device emulation:

• In macOS, press command + shift + M

There is a small button in the developer tools toolbar that enables device emulation, if you prefer to click a button rather than press a keyboard shortcut.

It looks like Apple have disabled by default the keyboard shortcut for entering responsive design mode. You can follow this tutorial on configuring a keyboard shortcut for it .

You can find the menu item by clicking "Develop", "Enter Responsive Design Mode". If you can't see the "Develop" menu item, you need to enable it by opening "Preferences", "Advanced", and ticking "Show Develop menu in menu bar".

• 1 Note that ctrl shift M works only if developer tools are already open –  Naramsim Commented Feb 6, 2018 at 10:29
• 3 @Naramsim Thanks. That only applies to Chrome. I've edited my answer. –  Flimm Commented Feb 6, 2018 at 11:19
• 3 For Windows/Chrome, F12 is a potentially easier way to get to Dev Tools... although if the next keystroke is going to be Ctrl-Shift-M, I suppose starting with Ctrl-Shift-I may be more logical. –  sǝɯɐſ Commented Feb 6, 2018 at 13:21
• I believe on previous versions of Safari Cmd+Shift+R would open responsive design mode. Seems to not exist on latest version unless you manually bind it –  Downgoat Commented Feb 6, 2018 at 23:52
• 1 Chrome remembers if you wanted a mobile preview, so once you've enabled it, you can toggle between mobile/desktop simply using F12 –  Pieter De Bie Commented Feb 8, 2018 at 12:26

Flimm’s answer is 100% correct. Just in case remembering the shortcuts is too much of a hassle, it’s this blue button in the Developer Tools to toggle between the web view and mobile/tablet view:

Or with Firefox:

After enabling the device toolbar, you can then choose the make and model of the device you wish to emulate from the dropdown menu.

• 1 What piece of software does the first part refer to? –  Kamil Maciorowski Commented Feb 7, 2018 at 5:22
• @KamilMaciorowski DevTools is the developer tool found in Chrome and Opera. –  OptimusCrime Commented Feb 7, 2018 at 7:46
• @KamilMaciorowski This is not a software, this is available on any of your web browser. Specifically if you're using chrome, right click on any window and click on inspect and you will see this window in your browser docked below or to the right of the browser. These are more commonly known as Dev Tools. –  Shobhit Garg Commented Feb 7, 2018 at 16:13
• @Shobbit Garg Is that the windows, which opens when I press CTRL + Shift + C? –  daniel.heydebreck Commented Feb 8, 2018 at 8:22
• @daniel.neumann Unfortunately I use mac, so I cannot test and see what happens when you press those keys. But referring to the shortcuts listed above, this window should open by pressing "ctrl + shift + I" on chrome, "ctrl + shift + M" on firefox or pressing f12 on IE/Edge. –  Shobhit Garg Commented Feb 8, 2018 at 15:04

For the purpose of testing, i use the following websites :-

• http://www.jamus.co.uk/demos/rwd-demonstrations/
• http://mattkersley.com/responsive/

Both of the above sites allow me to view my web application in multiple device widths.

You can set the user agent and window size from the command line or launch config of a shortcut.

For example:

& "C:\Program Files\Google\Chrome\Application\chrome.exe" --new-window --window-size=375,812 --user-agent="Mozilla/5.0 (Linux; Android 8.0; Pixel 2 Build/OPD3.170816.012) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/87.0.4280.67 Mobile Safari/537.36" --user-data-dir=C:\workspace\tmp\chrome https://google.com

The --user-data flag is mandatory to make this work . Create a folder for it.

Add a "user agent switcher" extension in your browser and specify a mobile user agent. If the website is smart enough it will serve you mobile optimized version.

I will not recommend any specific extension. The ideal one should have presets for mobile browsers built-in and the ability to enable or disable user agent switching on per-website basis.

• 1 This is incorrect. Mobile layouts should work based on device / screen dimensions via CSS media queries, not user agent strings - it's not 2006 any more. –  PiX06 Commented Feb 7, 2018 at 13:51
• Most browsers' tool that allows a mobile view also lets you set a user-agent at the same time. –  Flimm Commented Feb 7, 2018 at 14:33
• 1 @PiX06 then no effort is necessary. Just resize the browser window! –  Salman A Commented Feb 7, 2018 at 15:04
• Unfortunately, I find myself with many questions: If I'm resizing the browser window anyway, why do I need to bother with user agents? To which dimensions should I resize the window? How do I measure the window? –  Mathieu K. Commented Feb 9, 2018 at 5:26

The above answers are great for those who like to stick with a single browser, or have limited desktop "workspace" (eg. single monitor less than 21" at a low res).

There is actually an even more interesting solution I've recently discovered: https://blisk.io/

I will refrain from using the (sort of) "affiliate link" for any personal gain (There is a "token based system" that you can earn credits to get things like free "team cloud space" & "premium features" to use with it), but Blisk is actually pretty snazzy.

This Chromium-based "browser built for development" provides a multitude of ways to demo the page in various devices with a vertical "pane" on the LEFT side, much like you see Chrome Developer Tools default to the right vertical column.

It's work a look. Though there are some limits to its "freemium extended functionality", it still works very well to "preview" both the PC and Mobile versions of your pages / sites in a side-by-side comparison. The paid features seem pretty rad too if you work in remote teams (though I personally think it need a better "test drive" program before hooking people on the monthly cost).

Full disclosure: there is an EXTREMELY annoying "time limit" per day on the mobile preview part (toggles open/closed from the icon to the right of the address bar - change the "device preview" from the tiny link-to-the-menu in the top right corner "Show device list").

BliskDemoScreenshot

Also: I've found a few really nifty tricks with Browser Extensions like the 2 different "User-Agent Switcher"'s from Chrome/Firefox that go a bit further by letting you toggle between browser user-agent strings of various Operating Systems AND the browsers for them.

I prefer the "esolutions.se" flavor because of how easy it is to add custom user-agent strings to the list for as many customizations as you could ever want (runs offline also, which can be handy in certain cases): https://chrome.google.com/webstore/detail/user-agent-switcher/clddifkhlkcojbojppdojfeeikdkgiae

Anyway, that's my 2 cents. :P

Effective breakpoint usage is key for isolating issues:

• Set breakpoints directly within the source code
• Organize breakpoints into groups by context
• Use conditional breakpoints to pause on specific criteria
• Disable breakpoints without deleting to toggle behavior
• Manage breakpoints efficiently even in complex codebases

Mastering breakpoints gives you precise control over pausing execution to inspect logic flow and data.

Scope Inspection

Understanding scope is vital for tracking down variable issues:

• Inspect variable values in different call frames
• Detect scope pollution across closures and modules
• Ensure code executes in the intended lexical scope
• Fix bugs caused by accessing stale variable references
• Avoid global namespace pollution

With Safari's scoping tools, you can confidently debug even complex nested closures and callback contexts.

Async Debugging

Safari provides multiple approaches for debugging asynchronous code:

• Step through promise resolutions and rejections
• Inspect async operation call stacks and task queues
• Profile async code performance with CPU profiler
• Set breakpoints within async callbacks and timers
• Visually trace async code flows

Smooth async debugging helps you tackle race conditions, timing issues, and callback hell.

Error Handling

The key to debugging runtime errors is Safari's break on exception feature:

• Break on any caught or uncaught exceptions
• Inspect error call stacks to trace where issues originate
• Log values with console.log() to debug logic flow
• Validate edge cases and fix crashes
• Handle errors gracefully to improve user experience

With robust error handling, you can isolate bugs quicker and build more resilient apps.

Optimizing Page Speed

Next let's explore some common techniques for optimizing page speed using Safari developer tools.

Image Optimization

Safari provides multiple ways to optimize images:

• Audit image sizes and formats using the Resources panel

• Serve next-gen formats like WebP to Safari users
• Remove unnecessary decorative images

With Safari's insight into image resources, you can significantly cut page weight and load times.

Script Loading

Optimizing script loading is key for performance:

• Minimize parser-blocking JavaScript
• Load non-critical scripts asynchronously
• Dynamically create and load scripts
• Code split bundles into logical chunks
• Tree shake and minify code to reduce payload

Safari shows you exactly how scripts impact loading behavior so you can optimize delivery.

Caching Assets

Effective caching can boost repeat visit performance:

• Set optimal cache lifetimes for static assets
• Cache assets locally using service workers
• Version assets linked to app release cycles
• Avoid cache-busting query strings
• Maximize cache reuse for returning users

The Resources panel helps you dial in caching for faster loads without staleness.

Layout Thrashing

Diagnosing layout thrashing is key for smooth UX:

• Identify forced synchronous layouts
• Defer non-critical DOM updates with requestAnimationFrame()
• Avoid reading styles after writes during rendering
• Batch DOM reads/writes together
• Profile with Debugger to pinpoint problems

With Safari's performance tools, you can isolate and fix sources of jank and lag.

Wrap Up and Key Takeaways

Safari developer tools provide everything needed to build high-quality websites targeting Apple's ecosystem.

You’ve done a fantastic job setting up your Safari browser! Now, let’s delve into accessing and navigating the Developer Tools.

Step 1: Opening Developer Tools in Safari

• Click on the “Develop” menu in the menu bar.
• Choose ‘Show Web Inspector’ or use the shortcut – Cmd + Option + I (Mac) or Ctrl + Shift + I (Windows).

Voilà! The Developer Tools window is now at your disposal.

Step 2: Introducing Developer Tools Panels

Safari’s Developer Tools offers various panels, each providing unique insights and controls. Here’s a brief overview:

• Elements: Inspect and modify HTML and CSS in real-time.
• Network: Monitor network requests and analyze loading performance.
• Sources: Debug JavaScript code and manage project files.
• Timelines: Analyze rendering and scripting performance.
• Storage: Inspect and manage site’s cookies, local storage, IndexedDB, and more.
• Console: View messages, errors, logs, and execute JavaScript code.

Section 3: Leveraging Responsive Design Mode

With familiarity in the Elements panel, let’s make your website shine on mobile devices using Safari’s Responsive Design Mode!

Understanding Responsive Design Mode and Its Importance:

Responsive Design Mode in Safari’s Developer Tools simulates your website on different devices. This aids in identifying layout issues, testing media queries, and ensuring seamless functionality across devices.

Enabling Responsive Design Mode in Safari:

• Open Safari, visit your webpage.
• Click on “Develop” in the menu bar.
• Select “Enter Responsive Design Mode” or use the shortcut – Cmd + Option + R (Mac) or Ctrl + Shift + R (Windows).

Section 4: Pro Tips for Effective Mobile View Testing

You’re on the right track! Now, let’s discuss some essential practices and tips for efficient mobile view testing. By following these guidelines, you’ll be well-equipped to create an exceptional user experience across various devices.

• Test Early and Test Often:

Ensure mobile view testing is integrated from the design phase itself. Regular testing helps identify and rectify issues early, saving time and effort in the long run.

• Test on Multiple Device Presets:

While testing on every device is impossible, covering a diverse range of device presets is crucial. This includes different screen sizes, resolutions, and aspect ratios for comprehensive compatibility.

• Test in Both Orientations:

Accommodate user preferences by ensuring your website looks and functions well in both portrait and landscape modes.

• Test with Real Devices:

Simulators are valuable, but real hardware testing can reveal nuances that simulators might miss. Whenever possible, conduct tests on actual devices.

• Consider Touch Interactions:

Given the prevalence of touch-based interactions, make sure your site is user-friendly for touch gestures. Buttons and links should be adequately sized for easy tapping, and gestures like swiping and scrolling should work smoothly.

• Optimize Performance:

Mobile devices often have limited resources. Optimize your site’s performance by reducing image sizes, minifying JavaScript and CSS files, and leveraging browser caching. This ensures swift loading and smooth performance.

• Keep Accessibility in Mind:

Ensure your site is compatible with screen readers, and text is legible without zooming. Pay attention to color contrasts for users with visual impairments.

By adhering to these best practices and tips, you’re well on your way to crafting a website that offers a seamless experience on a wide array of mobile devices. Remember, diligence and attention to detail are key.

Section 5: Debugging and Element Inspection on Mobile View

With a strong foundation in mobile view testing, let’s explore how to debug and inspect elements using Safari’s Developer Tools. We’ll focus on the Elements and Console panels, and also touch upon optimizing performance using the Network panel.

Inspecting and Modifying Elements in Mobile View:

The Elements panel empowers you to inspect and interact with the HTML and CSS of your site in real-time, allowing you to refine your site’s appearance and layout.

• To inspect an element, right-click (or Ctrl-click on Mac) on the element within the Responsive Design Mode window and select ‘Inspect Element.’ Alternatively, you can click the “Inspect” icon (a magnifying glass) in the top-left corner of the Elements panel and then click on the desired element in the window.
• Once an element is selected, the Elements panel will display its HTML and CSS. You can click on any HTML attribute or CSS property to edit it directly in the panel. Changes will be reflected in real time within the Responsive Design Mode window, allowing you to experiment with different styles and layouts.
• Use the ‘Styles’ & ‘Computed’ tabs in the right-hand pane of the Elements panel to view and modify an element’s CSS properties, as well as to analyze how the browser is applying them.

Debugging JavaScript Issues with the Console Panel:

The Console panel is your go-to for debugging JavaScript issues on your site. It displays messages, errors, and logs, and allows you to execute JavaScript code directly.

• Open the Console panel by clicking on the “Console” tab within the Developer Tools window.
• Keep an eye on any error messages or warnings in the Console panel. These messages can help you identify issues with your JavaScript code, such as syntax errors or references to undefined variables.
• To execute JavaScript code directly, type your code into the input area at the bottom of the Console panel and press Enter. This is especially useful for testing functions or manipulating your site’s DOM in real time.

Optimizing Website Performance with the Network Panel:

The Network panel is a treasure trove for analyzing your site’s performance on mobile devices. It helps you identify bottlenecks and optimize load times.

• Open the Network panel by clicking on the ‘Network’ tab within the Developer Tools window.
• Reload your site within the Responsive Design Mode window. The panel will display a list of network requests made by your site, along with detailed information such as load times, file sizes, and response codes.
• Sort the network requests by size or load time to identify the largest or slowest-loading resources. This can help you pinpoint areas where optimization is needed, such as compressing images or minifying JavaScript and CSS files.
• Use the “Waterfall” view to visualize the order and timing of network requests, making it easier to identify potential performance bottlenecks.

By mastering the Elements, Console, and Network panels, you’re well-equipped to debug and optimize your website for mobile devices. Remember, a website that looks great and performs smoothly on mobile devices is crucial for providing an excellent user experience, so don’t hesitate to invest time and effort into perfecting your site’s mobile view.

In this comprehensive guide, we’ve delved into the power of Safari’s Developer Tools, equipping you to create a seamless and captivating mobile experience for your website. With these tools and practices, you’re ready to tackle mobile view optimization confidently. So, dive into Safari’s Developer Tools and make your website shine on all devices. Happy testing and optimizing!

Want to try out mobile websites designed for the iPhone and other mobile devices on your PC?  Safari 4 for Windows lets you do this easily with their developer tools.

By default, Safari will show standard desktop websites.  But by making a simple change, you can switch it to work like Safari Mobile on the iPhone or iPod Touch.

Getting Started

First make sure you have Safari 4 for Windows installed.  You can download Safari directly (link below) and install it as usual.

Or if you already have another Apple program installed, such as QuickTime or iTunes, then you can install it from Apple Software update.  Simply enter apple software update in the Start menu search box.

And then select Safari 4 from the list of new software available.  Click Install to automatically download and install Safari.

Accept the license Agreement, and then Safari will automatically install.

Once this is finished, Safari will be ready to use.

View Mobile Sites in Safari

First, we need to enable the developer tools.  Click the gear icon on the toolbar, and select Preferences.

Click the Advanced tab, and then check the box that says “Show Develop menu in menu bar”.

Once you’ve closed your settings box, click the page icon, select Develop, then User Agent, and then choose one of the Mobile Safari settings.  In our test we chose Mobile Safari 3.1.2 – iPhone.

To make your browser emulate a mobile device better, you can hide the bookmarks and tab bar to have a more streamlined interface.

Click the Gear icon, and select “Hide Bookmarks Bar”, and then repeat and click “Hide Tab Bar”.

You can also shrink your window to be closer to the size of a mobile device screen.  Once you’ve done these things, Safari should look similar to this screenshot.  Here we have loaded Google.com, and you can see it in its iPhone-style interface.

Simply enter any website into the address bar, and it will load in its mobile interface if it has one.  Here is Google’s other mobile offerings, right inside Windows.

Gmail loads messages with the default iPhone interface.

One especially interesting mobile site is Apple’s online iPhone User Guide .  When loaded in Safari with the iPhone setting, it loads with a very nice mobile UI that works just like an iPhone app.  In fact, you can even click and drag to scroll, just like you would with your finger on an iPhone.

Even if you do not have a Smartphone, you can still preview what websites will look like on them with this trick. Not all sites will work of course, but it’s fun to play around with different sites that have mobile versions.

PRESS RELEASE

The release introduces all-new customization options, the biggest-ever redesign of Photos, powerful updates for staying connected, and Apple Intelligence, the personal intelligence system

CUPERTINO, CALIFORNIA  Apple today previewed iOS 18 , a major release that features more customization options, the biggest redesign ever of the Photos app, new ways for users to manage their inbox in Mail, Messages over satellite, and so much more. Users will be able to arrange apps and widgets in any open space on the Home Screen, customize the buttons at the bottom of the Lock Screen, and quickly access more controls in Control Center. Photo libraries are automatically organized in a new single view in Photos, and helpful new collections keep favorites easily accessible. Mail simplifies the inbox by sorting email into categories using on-device intelligence, and all-new text effects come to iMessage. Powered by the same groundbreaking technology as existing iPhone satellite capabilities, users can now communicate over satellite in the Messages app when a cellular or Wi-Fi connection isn’t available. 1

iOS 18 also introduces Apple Intelligence , the personal intelligence system for iPhone, iPad, and Mac that combines the power of generative models with personal context to deliver intelligence that’s incredibly useful and relevant. 2 Built with privacy from the ground up, Apple Intelligence is deeply integrated into iOS 18, iPadOS 18, and macOS Sequoia. It harnesses the power of Apple silicon to understand and create language and images, take action across apps, and draw from personal context, to simplify and accelerate everyday tasks.

“We are thrilled to introduce iOS 18. It is a huge release with incredible features, including new levels of customization and capability, a redesigned Photos app, and powerful ways to stay connected with Messages. There are so many benefits for everyone,” said Craig Federighi, Apple’s senior vice president of Software Engineering. “This release also marks the beginning of a tremendously exciting new era of personal intelligence with Apple Intelligence delivering intuitive, powerful, and instantly useful experiences that will transform the iPhone experience, all with privacy at the core. We can’t wait for users to experience it.”

iPhone users have new ways to customize the Home Screen, Lock Screen, and Control Center. Users can now arrange apps and widgets in any open space on the Home Screen, including placing them right above the dock for easy access or perfectly framing a wallpaper. App icons and widgets can take on a new look with a dark or tinted effect, and users can make them appear larger to create the experience that is perfect for them.

Control Center has been redesigned to provide easier access to many of the things users do every day, and it gets new levels of customization and flexibility. The redesign delivers quick access to new groups of a user’s most-utilized controls, such as media playback, Home controls, and connectivity, as well as the ability to easily swipe between each. Users can now add controls from supported third-party apps into Control Center to quickly unlock a vehicle or jump right into capturing content for social media — all from one place. The new controls gallery displays the full set of available options, and users can customize how the controls are laid out, including adjusting them to the ideal size and creating entirely new groups.

For the first time, users can now switch the controls at the bottom of the Lock Screen, including choosing from options available in the controls gallery or removing them entirely. With the Action button available on iPhone 15 Pro and iPhone 15 Pro Max, users can quickly invoke controls available in the gallery.

Photos receives its biggest-ever redesign to help users easily find and relive special moments. A simplified, single view displays a familiar grid, and new collections help users browse by themes without having to organize content into albums. Plus, collections can be pinned to keep favorites easily accessible. A new carousel view presents highlights that update each day and feature favorite people, pets, places, and more. Autoplaying content throughout the app brings libraries to life, so past moments can be enjoyed while browsing. Because each user’s photo library is unique, the app is customizable, so users can organize collections, pin collections to access frequently, and include what’s most important to them in the carousel view.

iMessage receives all-new text effects that bring conversations to life by amplifying any letter, word, phrase, or emoji with dynamic, animated appearances. Users can better express tone by adding formatting like bold, underline, italics, and strikethrough. Tapbacks expand to include any emoji or sticker, and now users can compose a message and schedule to send it at a later time.

When messaging contacts who do not have an Apple device, the Messages app now supports RCS for richer media and more reliable group messaging compared to SMS and MMS.

iOS 18 introduces Messages via satellite for the times when cellular and Wi-Fi connections aren’t available. Powered by the same groundbreaking technology as existing iPhone satellite capabilities, Messages via satellite automatically prompts users to connect to their nearest satellite right from the Messages app to send and receive texts, emoji, and Tapbacks over iMessage and SMS. 3 With Dynamic Island, users always know when they are connected to a satellite. Because iMessage was built to protect user privacy, iMessages sent via satellite are end-to-end encrypted.

Later this year, Mail will introduce new ways for users to manage their inbox and stay up to date. On-device categorization organizes and sorts incoming email into Primary for personal and time-sensitive emails, Transactions for confirmations and receipts, Updates for news and social notifications, and Promotions for marketing emails and coupons. Mail also features a new digest view that pulls together all of the relevant emails from a business, allowing users to quickly scan for what’s important in the moment.

Safari, the world’s fastest browser, 4 now offers an even easier way to discover information on the web with Highlights and a redesigned Reader experience. Using machine learning, Safari can surface key information about a webpage. For example, users can review a summary to get the gist of an article; quickly see the location of a restaurant, hotel, or landmark; or listen to an artist’s track right from an article about the song or album. Reader has been redesigned to offer even more ways to enjoy articles without distraction, with a summary and table of contents included for longer articles.

Building on the foundation of Keychain, which was first introduced more than 25 years ago, the new Passwords app makes it easy for users to access their passwords, passkeys, Wi-Fi passwords, and verification codes. The app also includes alerts for users regarding common weaknesses, such as passwords that are easily guessed or used multiple times and those that appear in known data leaks.

iOS 18 gives users even more control with tools to manage who can see their apps, how contacts are shared, and how their iPhone connects to accessories.

Locked and hidden apps offer users peace of mind that information they want to keep private, such as app notifications and content, will not inadvertently be seen by others. Users can now lock an app; and for additional privacy, they can hide an app, moving it to a locked, hidden apps folder. When an app is locked or hidden, content like messages or emails inside the app are hidden from search, notifications, and other places across the system.

iOS 18 puts users in control by letting them choose to share only specific contacts with an app. In addition, developers now have a way to seamlessly connect third-party accessories with iPhone without letting an app see all the other devices on a user’s network, keeping a user’s devices private and making pairing seamless.

Deeply integrated into iOS 18 and built with privacy from the ground up, Apple Intelligence unlocks new ways for users to enhance their writing and communicate more effectively. With brand-new systemwide Writing Tools built into iOS 18, users can rewrite, proofread, and summarize text nearly everywhere they write, including Mail, Notes, Pages, and third-party apps.

New image capabilities make communication and self-expression even more fun. With Image Playground, users can create playful images in seconds, choosing from three styles: Animation, Illustration, or Sketch. Image Playground is easy to use, built right into apps like Messages, and also available in a dedicated app.

Memories in Photos lets users create the stories they want to see just by typing a description. Apple Intelligence will pick out the best photos and videos based on the description, craft a storyline with chapters based on themes identified from the photos, and arrange them into a movie with its own narrative arc. In addition, a new Clean Up tool can identify and remove distracting objects in the background of a photo — without accidentally altering the subject.

With the power of Apple Intelligence, Siri takes a major step forward, becoming even more natural, contextually relevant, and personal. Users can type to Siri, and switch between text and voice to communicate with Siri in whatever way feels right for the moment.

With Private Cloud Compute, Apple sets a new standard for privacy in AI, with the ability to flex and scale computational capacity between on-device processing, and larger, server-based models that run on dedicated Apple silicon servers. When requests are routed to Private Cloud Compute, data is not stored or made accessible to Apple and is only used to fulfill the user’s requests, and independent experts can verify this privacy.

Additionally, access to ChatGPT is integrated into Siri and systemwide Writing Tools across Apple’s platforms, allowing users to access its expertise — as well as its image- and document-understanding capabilities — without needing to jump between tools.

Additional features in iOS 18 include:
