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.
Xcode 8.3.3 includes Swift 3.1 and SDKs for iOS 10.3, watchOS 3.2, tvOS 10.2, and macOS Sierra 10.12

Good lord. . . - Raise your hand if you’re tired of people trashing a program because they have trouble downloading it. Sure, it may be an issue for some but when I, for one, look at an agerage rating in the App Store I expect it to be about the app itself. I understand frustration, especially with Apple not being highly responsive, but I think venting about the download process in a review is highly misleading. Aren’t there other more productive places to air this?
Breaking rules, ignoring standards - Not only is Xcode 6 significantly less functional than before (because features have been disabled pending the OS X Yosemite release), but it blantantly ignores Apple's own interface guidelines and standards. How is it okay for Apple to disregard the rigid standards they hold everyone else to? Why do they insist on forcing the hideous new design upon us even before the Yosemite release? They give us hideous, flat icons, they change the font, and make everything significantly brighter than in every other app they have out. What are they thinking? This would be perfectly alright in Yosemite, as it would fit in and contribute to the new design, but right now it just stands out. In addition to that, the progress bar is only two pixels tall. Think about that! My screen is 900 pixels tall, and two pixels is just insanely small! Apple, if you delete this review like the four I wrote before (which were VERY considerate and sounded much less hateful), I am going to stop using your products. You have already ruined my career, so stop preventing poor reviews from showing up.

Strange - It’s interesting to me that this is Apple proprietary — there is absolutely nothing else Apple needs to support with XCode — yet it still has a tremendous amount of strange quirks. Dependancy issues, build errors, emulator crashes, etc. Having worked with several other IDEs, I must say this is one of the worst I work with on a regular basis. Most other IDEs I use are supporting several OSes and several languages — Visual Studio for example. In VS 2015/2017 I rarely ever encounter issues that I can’t quickly resolve (typically something stupid on my part). This even includes building with heavy third party integrations (like Unreal Engine 4)! I’m not a Microsoft fanboy - in fact, I really despire most things Microsoft. However, VS is about 200 times better than this. Whenever I have build errors in Xcode (when developing for iOS in Objective C) it is typically extremely convoluted and exceptionally difficult to figure out where the actual issue is. It’s bizzarre to me that we are in 2017 and an IDE is as terrible at error reporting as XCode is. All in all, I’ve actually stopped developing for iOS in XCode. In fact, due to weird quirks that really hamper productivity (Apple IDs on business computers that shuffle to different users now and then for example — good luck to anyone doing that!) we’re completely eliminating XCode from our pipeline. I’ll spare everyone to details that could potentially seem like a sales pitch. Bottom line is we’re sick of Apple’s weird quirks.
If I were Apple, I would be embarrassed - 6/24/2017: Another broken release - shocker. Intellisense has taken a hit. Do you test your software at all? You used too. What happened? Intial Review: As others have reported, I could not just get the latest version of XCode. It would sit there an spin without any kind of status. To get past this, update your OS to El Captain. Then you can down load XCode from the store. I am not giving a bad review because of this poor download/release installation. Now that I have been using the 7.3 version, I am constantly doing a “Clean” as it won’t pick up my code changes and gives me bad access at times. It’s trying to optimize build time by trying to determine what changed and what needs to build… thus, gets it wrong and you have to force it to build all with a clean product commond. This is one of the worst versions of XCode stability that I have ever seen. I bet, there will be a patch to fix this kind of behavior. I am starting to lose faith in doing apps for Apple. I am on my first and It’s nothing but problems when they update iOS and/or XCode. Very poor quality.
Why you remove el capitan support? - Great job Apple! I updated my iPad to latest iOS version and than trying to update my Xcode to continue my work. But i can’t, becose you remove previos macOS version. Previos! Why i paying you 100 bucks for developer account, if i can’t work on my mac pro early 2009?
Just finished the installation process… - After Dr. Mengueche fixed all the installation problems that I was having now the time has finally come to test it…
Been trying to update all night - I’ve been trying to update all night. Its been several hours. I just keep getting a spinner and no indication that it has completed or is done updating. Trying to actually do some programming...
