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.

Avis des utilisateurs
Too many bugs and lack of some basic features
This release of XCode contains too many bugs and lacks of features…
- Project doesn’t re-open correctly (no files on the left navigator, bad syntax and references on the files opened), force us to close and open again the project.
- When you select an item on the interface builder, the item is not set as selected on the properties editor or you cannot move with the arrows keys… I select the item like a button or other directly, it said that there is nothing selected. Thanks to this bug, I realized that I can modify the file as text and increase a frame...
- You can’t do basic things… I don't even know if it is possible to duplicate a line without selected them, copy, paste… And some awesome plugins who do this, doesn’t work when XCode is updated.
Bad buggy new release
This new release of XCode has been released by far too early. It is not mature, and has many severe bugs or annoying problems.
* Can’t read old XIB files without crashing - worse, as you re-start, XCode will try to read this same XIB file that made it crash and… crash again. The only solution to get out of this crashing loop is to remove the XIB file from its folder in the finder so that XCode don’t find it any more
* Over flooding the console with XCode internal messages. This is making your real NSLogs into tons were useless information.
* Some framework don’t work at all any longer, such as CNContact (mac OS only, iOS is OK). Any access to the CNContact store returns a nil CNContact.
And many ohters...
The best advice I can give is to wait for 8.1...
worse ide ever
Unstable, lacking basic features (refactoring, code formatting [real one], etc.), a terrible project setup format that is a nightmare for version control. The list of problems qith this ide is so big that they should start over (with the UX)
Apple make everything they can to make it impossible to have a competitor for this ide and there is almost no way to develop for iOS with something else so we have no choice.
