What’s new in Swift
Dive into the latest features and capabilities.
Swift 6.2
Swift 6.2 comes with a powerful new set of features focused on performance. Updates to concurrency make asynchronous and concurrent code easier to write correctly. And with Inline Arrays, you can declare fixed-size arrays, allowing for optimizations at compile time. The new Span type provides a safe alternative to unsafe buffer pointers. Improved interoperability with C++, as well as expanded support for interfacing with Java, makes it easier to adopt Swift in your existing apps.
Concurrency
Concurrency helps you improve app responsiveness and performance, and Swift is designed to make asynchronous and concurrent code easier to write correctly. With new Swift compiler configurations available in Xcode’s build settings, and multiple Swift language updates — like the addition of the new @concurrent attribute — you can adopt concurrency when and where you need it.
Interoperability
You can incrementally adopt Swift in your existing C, C++, and Objective-C apps to make your code safer and more efficient. And with the swift-java interoperability project, you can now bring Swift into your Java code.
Containerization
Say hello to Containerization — an open source project written in Swift and optimized for Apple silicon, designed to create and run Linux containers on your Mac.
