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.

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.
More Reviews for Current Version
Do not download if you acctually want to submit your applications - itunes connect will not accept builds from this version of Xcode. This application should have been rejected as non functional from the app review team.
A beta version was deployed to the AppStore?? - I didn’t find any bugs, but when I tried to submit my app to the AppStore, I got a message back saying that my Xcode was the beta version. I deleted Xcode completely and reinstalled it fromt the AppStore, and the problem continues. Command Line Tools setting claims this is Xcode 9.2 (9C40b). I stayed until 3:00am last night for nothing as I couldn’t submit my app!
Xcode 9.2 - This version of Xcode, as other reviews here are saying, does not play well with High Sierra. Until I read those reviews I thought I had messed something up, although I have completely removed and re-installed Xcode twice now. The one good thing I can say is that playgrounds are crashing slightly less than in 9.1. Aside from that, this app is shockingly bad. I can’t believe Apple has done nothing to respond to all the unhappy users! It crashes, loses its mind trying to get constraints working in IB, and often if I try to set a label to >1 line the entire view in storyboard just turns gray, no way out except try to find a setting for number of lines that will work - sometimes even #s work, other times only odd #s work. I admit it is an extremely comprehensive app with a lot of wonderful features. But in its current state those feaures mean nothing. The reviewer who said it’s like trying to run a program on windows 95 was correct! Just plain buggy as hell. Apple, you need to do a complete rewrite of this piece of crap!
Apple should feel ashamed - The worst IDE I’ve ever used. Xcode is billed as, “...a complete developer toolset for creating apps for Mac, iPhone, iPad, Apple Watch, and Apple TV.” Well, it’s complete...something, but a developer toolset it is not. It screws my file structure up, is slow, and sometimes the text editor can’t even keep up with typing. Yes, the text editor often has significant delay from typing to letters appearing on the screen, which you’d think an “innovative” company like (cr)Apple would have figured out by now. It would seem to the user of Xcode that Apple’s apparently lousy engineers have spent most of their time innovating new ways to frustrate the developer. The compilation process is like watching paint dry except I’d have had more fun painting drywall than working with Xcode. Getting help from Apple is also a chore and not recommended. Leave the Apple ecosystem if you want to maintain your sanity. I note that there is a link right above the section I’m typing telling me that, “If you need support, please visit Xcode Support”. Given the poor reviews here (and the fact that you WILL need support when using Xcode) I can see why Apple would do that, but the help page is just more nonsense. A page to “help” you help yourself or spend a while trying to find a contact number that will give you a human on the other end without spending hours filling out forms. Anyone I know would feel ashamed to be associated with this product. If you work at Apple you should feel ashamed to have to support this product. Completely embarrasing for Apple engineers to consider this even a beta, much less release it like it’s actually a productive program. The word that comes to mind is embarrasing. How one of the most profitable companies on the planet can release such garbage is beyond me. Completely embarrasing Apple; what a farce.
Apple needs to step it up - Xcode is always giving me problems. One minute,my code works. Then all out of nowhere, certain parts of my code doesn’t want to work and Xcode crashes. If Apple can’t handle the expectations of the IOS developer family, just simply allow somebody else to develop Xcode
