A new Swift blog post/announcement has been posted!

We’re delighted to announce the general availability of Swift 6. This is a major new release that expands Swift to more platforms and domains.

Many people know of Swift as a language for app development, with a million apps on the App Store. But Swift is great for more than just apps. Swift’s safety, speed, and approachability make it a great choice for many other use cases including libraries, internet-scale services, and the most performance-critical and secure code.

Swift 6 scales even further through new low-level programming features, an embedded Swift language subset, expanded Linux and Windows support, new cross-platform APIs including the new Swift Testing library, and more.

Read on for a deep dive into changes to the language, standard libraries, debugging, platform support, and next steps for getting started with Swift 6.
