We think everyone should have the opportunity to create something that can change the world. Code powers virtually everything around us.

List of 11 best Mac apps for developers

When you turn your car on, code lets your key talk to the engine. When you want pizza, code places your online order. When you want to know if you should eat that pizza, code helps you keep track and decide.

Best Programming Apps for Mac

We designed Swift to be easy to use. Type your code on the left and immediately see the result on the right. We put as much thought into how you learn Swift as we put into designing the language itself. Learn more about Swift Playgrounds.

We created a comprehensive Everyone Can Code curriculum to help you teach coding to students from kindergarten to college. With teacher guides and lessons, you can introduce the basics on iPad, then advance to building real apps on Mac. A more detailed look at Swift for coders at every level.

macOS Development for Beginners: Part 1

Learn more about Swift. Educator Forums about the Developer Site. Swift already supports all Apple platforms as well as Linux, with community members actively working to port to even more platforms. To learn more about the open source Swift community, visit Swift. Swift 3 set up the language for source-level stability and now Swift 4 delivers source compatibility as a feature moving forward. Instead you can start using the new Swift 4 compiler and migrate at your own pace, taking advantage of new Swift 4 features, one module at a time.

Swift is the result of the latest research on programming languages, combined with decades of experience building Apple platforms. Named parameters brought forward from Objective-C are expressed in a clean syntax that makes APIs in Swift even easier to read and maintain. Inferred types make code cleaner and less prone to mistakes, while modules eliminate headers and provide namespaces.

These forward-thinking concepts result in a language that is easy and fun to use. Much like Swift Playgrounds for iPad, playgrounds in Xcode make writing Swift code incredibly simple and fun. Type a line of code and the result appears immediately. You can then Quick Look the result from the side of your code, or pin that result directly below.

The result view can display graphics, lists of results, or graphs of a value over time. You can open the Timeline Assistant to watch a complex view evolve and animate, great for experimenting with new UI code, or to play an animated SpriteKit scene as you code it. Use Swift syntax to evaluate and interact with your running app, or write new code to see how it works in a script-like environment. Available from within the Xcode console or in Terminal. Introduced in Swift 3, Swift Package Manager is a cross-platform tool for building Swift libraries and executables, making it easy to create and manage dependencies.

New API lets package authors define which products their packages make available to clients, and customize how their sources are organized on disk. And the overall API used to create a package is now cleaner and clearer, while retaining source-compatibility with older packages.

From its earliest conception, Swift was built to be fast. Using the incredibly high-performance LLVM compiler, Swift code is transformed into optimized native code that gets the most out of modern hardware. The syntax and standard library have also been tuned to make the most obvious way to write your code also perform the best. Swift is a successor to both the C and Objective-C languages. It includes low-level primitives such as types, flow control, and operators.

It also provides object-oriented features such as classes, protocols, and generics, giving Cocoa and Cocoa Touch developers the performance and power they demand. Swift eliminates entire classes of unsafe code. Variables are always initialized before use, arrays and integers are checked for overflow, and memory is managed automatically. Syntax is tuned to make it easy to define your intent — for example, simple three-character keywords define a variable var or constant let.

Another safety feature is that by default Swift objects can never be nil. In fact, the Swift compiler will stop you from trying to make or use a nil object with a compile-time error. This makes writing code much cleaner and safer, and prevents a huge category of runtime crashes in your apps. However, there are cases where nil is valid and appropriate. For these situations Swift has an innovative feature known as optionals.
