Xcode provides everything developers need to create great applications for Mac, iPhone, and iPad. Xcode brings user interface design, coding, testing, and debugging all into a unified workflow. The Xcode IDE combined with the Cocoa and Cocoa Touch frameworks, and 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, iOS Simulator, the latest OS X and iOS SDKs, and hundreds of powerful features:
Innovative tools help you create great apps
• Swift is a revolutionary new programming language that is safe, fast, and modern
• Playgrounds are a fun place to experiment with Swift code, displaying instant results
• Interface Builder is a graphical UI design canvas with a live preview of your app
• 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-it can correct the mistakes for you
Swift is an all new programming language for Cocoa and Cocoa Touch
• 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
- 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
• Preview your interface in different screen sizes, orientations, or languages
• 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
Apple LLVM technology finds and fixes bugs for you
• Analyzer travels countless code paths looking for logical errors before they become bugs
• Live Issues underlines coding mistakes as you type with no need to build first
• Fix-it can confidently correct mistakes for you with just a keystroke
Test driven development is built right in
• Use the Test Navigator to add, edit, or run 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 OS X Server to automatically build and test your apps
• Monitor performance test data using OS X Server to immediately spot regressions
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 you must be a member of Apple's iOS Developer Program. To submit your Mac or iOS apps to the App Store you must be a member of the Mac or iOS Developer Program. Continuous integration features require a current version of OS X Server. Some features may require Internet access.
What's New in Version 6.3
Includes Swift 1.2 and SDKs for OS X 10.10 Yosemite and iOS 8.3
New in Swift 1.2:
• Incremental builds dramatically improve the compile time of Swift projects
• Swift compiler produces even faster executables for both debug and release builds
• Language refinements to 'let' and 'as' make Swift more consistent and clear
• Standard library adds powerful features including the 'Set' data type and 'flatMap' operation
• Code converter and Fix-its help you migrate to Swift 1.2
Additional features in Xcode 6.3:
• Playgrounds are more attractive and readable with rich text formatting and results displayed in-line
• Playgrounds can embed additional code and resources to improve performance and simplify sharing
• Updated OS X SDK includes support for the new Force Touch trackpad
• Crashes organizer makes it easy to triage and fix crashes for App Store and TestFlight apps
• Apple LLVM compiler 6.1 improves diagnostic messages and adds support for C++'14
• Additional bug fixes and stability improvements
Seems like minimalizing during tapping "stop" is finally fixed.
-- update --
Every 3-4 time compilator is crashing almost immediately when I tap 'run'. Seems it doesn't even start to compile sources. Tried deleting derived data- doesn't help. Happens on various projects.
Happening after updating to Yosemite and xCode 6.1.
MacBook Air 11', mid 2011, 4GB RAM, 30GB free SDD space.
-- update --
I've found the reason why it's 'crashing'. You have the normal close, minimalize and fullscreen buttons on top left. Now when you run the app in fullscreen, these buttons slide out but only visually. If you tap in place that was used via such button - the button works even though it seems it isn't placed there any more. It happened multiple times that I've tapped stop and the app went out of fullscreen but didn't stop. If you tap 'run' in position, that usually is taken by 'close' button your project closes down. You can easly bypass it - just don't tap start button, use cmd+r or don't run Xcode in fullscreen... Still this should be fixed ASAP!!!
Good vs bad.
I understand that coming up with a perfect build of this is very difficult and that the occurences of bugs and crashes are hard to pinpoint because every user is doing something different with their project configuration and such. But using IBDesignable in storyboards or nib files causes crashes whenever i try to manually move the designable uielement or switch to a different file. The thing just pinwheels. And i have to clear it and reclone it from git to get anything done. Very irritating as i need to be careful now with the files. I’m going to try to reinstall xcode and see if that helps but otherwise this xcode release has more annoying bugs than other bugs for me.
Xcode 6.3 is a Disaster
Upon updating to version 6.3, all of my iOS devices showed as "ineligible devices". I've tried all the tricks posted on the web, tried removing and re-creating all my certificates and profiles, tried deleting caches, etc, but no luck yet. The problem continues to persist, across multiple devices, multiple projects, and even multiple dev accounts. Already wasted 4 hours on this mess. Very costly to productivity.
It also freezes up on me frequently when I start it with one of these devices plugged in.
