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.
What's New in Version 8.3.2
Xcode 8.3.2 includes Swift 3.1 and SDKs for iOS 10.3, watchOS 3.2, tvOS 10.2, and macOS Sierra 10.12
Xcode 8.3.2 improves performance and fixes several critical bugs, including:
• Swift projects using whole-module optimization now build faster on multi-core Macs
• Swift migrator now applies all applicable Fix-it conversions
• Fixed an issue that could prevent iOS playgrounds from supporting interactivity on non-Retina displays
• Fixed a compile failure when building valid C++ code involving a nested struct, enum, or lambda
• Fixed an issue where the debug console would not show output until a new line was printed
• Additional bug fixes and stability improvements
Best version of Xcode EVARRRR!
"This is the Best Version of Xcode, ever!”™ Seriously, though, to the reviewer who is having serious issues with syntax highlighting and so forth: The problems you describe are not expected behavior for pretty much any 8.x versionof Xcode, but I’ve seen similarly weird things happen on rare occasion. What seems to be happening is that something gets horked and then stuck in the cache or other temproary files. Get the to GitHub and look for the Gist called “xcode-nuke-uninstall” . If you wipe out Xcode and all, I mean *all* of its temporary files and settings, and then resinstall Xcode your issues should clear. You’ll need to open the Xcode preferences, go to Accounts, and log Xcode into your ADC account, after re-installing. Best wishes!
I love Xcode!
I Love Xcode ! It Does EveryThing so Much Better Than Visual Studio. however As A Student When i Strated Programming in C++ i Had To work with basic file handling ! XCode by default Creates those files to some really unaccessible location! this was a mess for me at that time! then i came across some solution on using edit schemes..to create files to folder where the project is ! so This Process shoud be simplified! Because For A student this small thing can be a real mess!
After three 3-hour attempts on a wired connectrion, with the little spinning busy indicator going, nothing ever gor downloaded. So, since I made the mistake of upgrading to iOS 10.3 on my iPhone, Xcode 8.2.1 won't let me run my app on it. Without Xcode 8.3.1, I'm stuck using the Simulator. Thanks, Apple!
