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 9.2 includes Swift 4 and SDKs for iOS 11.2, watchOS 4.2, tvOS 11.2, and macOS High Sierra 10.13.2
• Updates to the latest platform SDKs
• 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.
More Reviews for Current Version
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!
Buggy and annoying - I’ve been using Xcode for more than 7 years. Xocde has been getting worse and worse. Apple’s software is getting worse, user friendly but terribly buggy
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.
Very disappointing product... - This is the ONLY tool that we can use to develop iOS apps using Swift. It is not like we have any other choices. Given that is the case, it is of utmost importance that Apple makes sure that the product is HIGHLY STABLE and fast. Both marks are being missed there. Furthermore, too many changes made in the Swift language that breaks existing code. Its as if it is a proud religion within Apple to break things for the “better”. Or is it more like patching up indecisive decisions… If Apple cannot do a good job, maybe allowing third party developers to build development tools is a better idea. Simple things in Xcode 9.1 such as Time Profiler is broken. Have anyone there in Apple heard of automated testing?
Do not update!! - If you are still on 9.1, do not update to this version! It is completely not ready. Submitting to the store is broken after update due to some stupid bug. There are some other things broken as well.
