Open the Mac App Store to buy and download apps.
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 6.4
Xcode 6.4 adds support for iOS 8.4
Xcode 6.4 includes Swift 1.2 and SDKs for OS X 10.10 Yosemite and iOS 8.4
Rocky upgrade, but overall love
After updating to 6.4 this morning, it crashed every time I opened my main workspace, just when indexing started. I was able to get past this by nuking my Derived Data folder. I then had problems getting it to actually run my app in the simulator, but I saw a Software Update for command line tools going through in the background, which may have thrown a wrench in the works. After that finished and a restart just for good measure, things appear to be functioning properly.
Bottom line: I love Xcode, but today the software update gods were not on my side.
After all these versions, we still have to deal with certificates...
Why can’t i purchase my yearly subscription and assign 5 computers by just signing into my account like I do with iCloud? Why do I have to waist my time switching from a developer to a submission to the store? What is the difference between those two?
I should be able to simply DEVELOPE and SUBMIT just as easily without having to do anything more than click on a different button, one for installing on a local portable or desktop for personal testing or use, and one for “share” or submitt to the store.
What is so difficult about doing this?
It’s the best option but, could be better.
Apple, can we use other languages not just objective-c and swift (Ok there is more than that)! I mean you can download some plugin but, how about add some support into the program and how about this a plugin app store. If at least on off these happen I will go 5 stars.
