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 8.3.2 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

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.

Syntax could get easily crashed - Ever since Xcode starts supporting swift syntax, the Syntax Highlight feature’s been getting more unstable, especially from swift 3.x +, i’ve been working with almost no syntax highlights (except for basic colored key words in swift syntax), no auto-completion pop-up suggestions for like nearly half a year now, i have to separately prepare a doc, pasted mostly with all the most used auto-completion suggestions to go on with my code life, it’s devastating to code efficiently without auto-completion suggestions nowadays, very counter-productive Now the 8.3.x version is killing me, syntax highlight function will randomly crash even with all the legal syntax (i suppose, at least tell me briefly where caused the crash so i.could better my codes), i used to enjoy so much developping apps with Xcode, so easy and intuitive to use, and now i’m very much heart broken struggling with it. Maybe it’ll work like a charm again as it did with Objective-C
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 hate you Xcode! It’s useless now after the update - I’m currently learning C in college; the professors and computer labs normally use Windows, so they use Microsoft Visual Studios as the compiler. I’m a Mac geek and I quickly learn that I can use Xcode instead; and it turns out better than expected: -Boot up faster than Visual Studios -I can switch from C files to C files on the left hand panel by just clicking on it; and I can run if I deactivate the other files with just two simple steps: misspleing main and unchecking Target. -So I can run multiple C files by just doing the step listed above. -Love the fact that it’s Mac OS X compatible. -Simpler to use than MS Visual Studios. That’s just my experinces, I was a ble to run some basic math programs; however, I’m still learning and have yet to construct more complex programs to really test if Xcode will keep up with me. *Update 4/19/2017 After the update, xcode became an annnoying nightmare. I still use for school, however the issue is that the console does not show any output on the console window, unless I print a newline. I literally have to do this for every code segment, and it distorts my output from the way I want to look. I tried calling Apple Technical Support but all they did was refer to their website. So I then contact Xcode support by sending them a message, they replied to me with a message and then I think my case got close, however I did not understand a word in their reply. It was as if I was reading Chinese on a handbook. I hate you Xcode. I don’t understand why you can’t fi such a simple bug on Xcode. Curse you and your dumb compiler, it’s holding me back from my coding classes.
Takes some getting used to - Not bad. For what it is it works.
worse than before, but better than the next version - The worst Xcode yet. The debugger is slow. After pushing a button, or doing any action on sim, there is a long and annoying delay before the break point is hit in code. Sometimes the breakpoints are not even hit on the action. And then have to repeat the action over and over until finally the breakpoint is hit. Randomly crashes. All of this worked before updating to the last versions. Are you guys trying to alienate developers? Feels like only incompetents are working at Apple.
