Xcode includes everything developers need to create great applications for Mac, iPhone, iPad, Apple TV, and Apple Watch. Xcode provides developers a unified workflow for user interface design, coding, testing, and debugging. The Xcode IDE combined with the Swift programming language make developing apps easier and more fun than ever before.

Xcode includes the Xcode IDE, Swift and Objective-C compilers, Instruments analysis tool, simulators, the latest SDKs, and hundreds of powerful features:

Innovative tools help you create great apps
• Swift is a revolutionary programming language that is safe, fast, and modern
• Playgrounds are a fun way to experiment and interact with Swift code
• Interface Builder displays pixel-perfect UI for each target device and can edit at any zoom level
• View debugging shows a 3D stack of all your app's UI view layers at runtime
• Assistant editors show content related to your primary task
• Live Issues display errors as you type, and Fix-its can correct mistakes for you

Swift is a powerful, modern, and fun programming language
• Safe by design, Swift syntax and features prevent entire categories of bugs
• Fast code execution and compile time are powered by the proven LLVM compiler
• Modern language features are inspired by leading research, including:
- Closures unified with function pointers
- Tuples and multiple return values
- Structs as value types that support methods, extensions, protocols
- Powerful protocols that can extend functionality throughout your codebase
- Functional programming patterns including map and filter

Interface Builder makes it easy to design your interface without code
• Storyboards let you arrange the complete flow of screens within your app
• See your custom controls rendered live within the design canvas
• Customize your interface for different devices, screen sizes, and orientations
• StackViews make it easy to reason about the layout of each section of your interface
• Create connections from your GUI design directly to the related source code

Professional editor and debugger keep your code front and center
• Hit a few keys and Open Quickly will instantly open any file within your project
• Message bubbles show errors, warnings, and other issues right beside your code
• Data tips show a variable's value by hovering your mouse over the code
• Quick Look variables while debugging to see the actual color, bezier path, image, and more
• Third party app extensions can add new capabilities to the source editor

Test driven development is built right in
• Use the Test Navigator to add, edit, or run unit tests or user interface tests with just a click
• Test Assistant makes it easy to edit your code and related tests, side-by-side
• Create continuous integration bots using macOS Server to automatically build and test your apps
• Monitor performance and user interface test data using macOS Server to immediately spot regressions
• Analyzer travels countless code paths looking for logical errors before they become bugs

Instruments makes performance analysis beautiful
• Compare CPU, disk, memory, and OpenGL performance as graphical tracks over time
• Identify performance bottlenecks, then dive deep into the code to uncover the cause
• Monitor your app directly, or sample the entire system, with very little overhead

To test or deploy applications on an iOS device, Apple TV, or on Apple Watch all you need is a free Apple ID. To submit your apps to the App Store you must be a member of the Apple Developer Program. Continuous integration features require a current version of macOS Server. Some features may require Internet access.

Customer Reviews

stuck installing @3% 4 ever

After reading the many “positive” reviews of this upgrade i guess i should be glad that apple won’t let me upgrade (going on since update first became available),


Xcode’s syntax highlighting is completely broken. We have a large and complex project. While Xcode 7 was able to provide proper syntax highlighting and symbol inference, Xcode 8.2.1 completely gives up and bails out. This is all Objective-C code so no Swift to be found. I guess in their zeal to provide a half-baked language (Swift), Apple has gone ahead and broken support for Objective-C. What’s the point of an IDE if basic things like commenting code, syntax highlighting, and code suggestion don't work? Xcode’s been reduce to a bloated multi-gigabyte glorified text editor that crashes constantly without any usable features.

Also, once storyboards and asset catalogs are up opened by Xcode 8 they cannot be edited with an earlier version. I suppose this would be OK (there goes the Stockholm syndrome) except that Xcode 8 actually breaks all the storyboards. So we end up with broken storyboards that cannot be fixed. Starting over isn’t an option, as you might imagine. Had we maintained our UI in code instead of adopting Auto Layout, we wouldn’t have to deal with these issues.

I wish Apple did any QA but they don’t care.

Application Loader does not work

Unable to sign into my iCloud account via Application Loader. My regular password doesn’t work and prompts me to use an app-specific password, which I set up on my iCloud, but that doesn’t work either. Keep getting the error that I entered it incorrectly after I copied and pasted. I even tried entering it in manually with and without the dashes. No dice.
