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.
What's New in Version 8.3.3
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
Xcode 8.3.3 adds Interface Builder support for iPad Pro (10.5-inch)
A good developer tool that can be better.
An app so complicated like Xcode, comes with a huge stack of features, APIs, SDKs, that one wouldn’t actually use them all. Of course, an app that’s the mother of apps, so huge like this, is bound to come with imperfections and many head-scratching bugs. My biggest complain right now is how broken XCTest and its tools are (both of which I filed bug reports months ago). Accessibility Inspector, for example, fails to recognize UI elements even in the very basic setting that closely mirrors the WWDC talk. However, I appreciate many things Xcode provides, and some of them may have been underappreciated after years of its introduction, like Storyboard, Interactive Swift Playground, and continuous additions of new SDKs. Overall, I’d still rely on and recommend Xcode, but I also wish that bugs are ironed out and patched more quickly.
Hopeful for Xcode9, but currently needs work
I am excited about some of the improvements coming in the fall, but this current version can be quite a pain to work with. Often, the syntax highlighting and auto-complete features break which can be very inconvenient. Sometimes, Xcode fails to even recognise classes I have written and gives me build time errors even when my project is configured correctly and I’ve imported everything I should need. I really hope Xcode9 fixes these issues since it greatly hampers my productivity at work sometimes. When these buggy problems aren’t happening, I don’t mind working with Xcode but it happens far too often.
Regular Expression Search is Broken
I use search very often when developing and I tried to perform a search via regular expression, and the application generated the pinwheel of death. After having to force close Xcode, now any time that I try to do any kind of search, the application crashes.
