Open the Mac App Store to buy and download apps.
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 Cocoa frameworks and 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 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-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
• Preview your interface in different screen sizes, orientations, or languages
• 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
Apple LLVM technology finds and fixes bugs for you
• Analyzer travels countless code paths looking for logical errors before they become bugs
• Live Issues identifies 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 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 OS X Server to automatically build and test your apps
• Monitor performance and user interface 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, 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 OS X Server. Some features may require Internet access.
What's New in Version 7.1.1
Xcode 7.1.1 improves stability and fixes critical issues in Interface Builder, debugging, and UI testing.
Xcode 7.1 includes Swift 2.1 and SDKs for iOS 9.1, watchOS 2, tvOS, and OS X 10.11 El Capitan.
Now you can go beyond the simulator to test your app on an iPad, iPhone, Apple TV, or Apple Watch — for free. Simply enter your Apple ID into the Accounts preference pane, then attach a device to your Mac using a Lightning cable. You can use the same Apple ID you already use for iCloud, iTunes, or the App Store, or create a new one. Join the Apple Developer Program when you’re ready to distribute or submit your apps to the App Store.
New in Xcode 7.1:
• Support for tvOS including storyboards, unit and UI testing, and playgrounds
• New workflow to add a device for development and testing, select Window > Devices then click the + button
• Storyboard support for 3D Touch gestures
• View debugger presents an improved view of Auto Layout contraints at runtime
• Enhanced XCPlayground API gives playground authors more power
• Swift 2.1 improves interoperability with C code
• Two-factor authentication support when adding an Apple ID account
Xcode on App Store has been pretty bad
I’m not new to Macs, been using them for about 2008. But I never really used the app store much until recently when I purchased a Macbook Air for school. Now, I’m using the App store to download as much as I can to make updating apps super easy. One thing that has been severly lacking is Xcode updates. Half of the time, I cannot get the updates to start. I frequently have to exit and open the app store and try multiple to get the update to work. And when it does work, half o the time, in the App store, it does not show that it is downloading, you must look in Launchpad to know, as in the App store, it will continue to say “Update” and give the user the option to click to update. Futhermore, after it downloads, it will continue to take 20-30 minutes trying to install and eventually show that it never fully downloaded until you exit the app store (making you think it didn’t install), only to finally install later. This process has happened the past 4-5 times I’ve updated Xcode and has not been fun at all. I really hope the process of updating Xcode exponentially gets better, as its pretty bad right now.
Full of bugs from the start
I have been trying to install the 7.1.1 update all day. It just gets stuck towards the end of the installation. It should not take this long to update.
The previous version was full of bugs. Archive failed often while compiling the storyboard. Uploads to iTunes Connect failed often. Plus an assortment of APIs that do not function as documented. The latest was with Swift’s sortInPlace which doesn’t work in release mode.
Update: After almost 12 hours of trying, I finally got 7.1.1 to install. Uploading to iTunes Connect is no better and failed on the first and second try with the dreaded “Cannot verify client (3000)” error. The warning about the API analysis file being too large is still there as well.
Updating Xcode Is The Most God Awful Experience
Just like other users when you try to updated Xcode it takes a long time for the App store to start the process. Then when the process does start you have to go to the launch pad to see if it is working because the App Store will just return the update button back to a clickable button with no timer. I am running Xcode on two machines a Macbook Pro 2011 and Macbook Air 2015 both have experence tremandace errors and issues trying to get this update. On one everytime I try to update the App Store starts downloading a brand new copy of Xcode (4.3GB) and does not convert back to just the update (156MB). The other got all they way to the installing part and then just stoppped restarted my computer and gave me the option to start over. Horrible execution.
