Swift 6 introduces several significant improvements and new features aimed at enhancing portability, performance, and the overall developer experience. Here are some of the key updates:
-
Data Race Safety: Swift 6 introduces a new language mode that provides data race safety guarantees, helping developers write correct concurrent programs. This mode is opt-in and can be adopted module by module, allowing for incremental migration (Platforms State of the Union).
-
Non-Copyable Types: Swift 6 introduces non-copyable types, which are types that cannot be copied. This feature helps in managing resources more efficiently and avoiding unintended copies (What’s new in Swift).
-
Embedded Swift: A new language subset called Embedded Swift is introduced, which can run on highly constrained systems like operating system kernels and microcontrollers (What’s new in Swift).
-
Concurrency Improvements: There are significant improvements to concurrency, including better data race checking and complete concurrency checking. Swift 6 can recognize safe scenarios for passing non-sendable values across isolation boundaries (What’s new in Swift).
-
Swift Testing: An all-new testing framework named Swift Testing is introduced, which has expressive APIs that make it simple to write tests (Platforms State of the Union).
-
GitHub Organization: Swift is moving to a new organization on GitHub,
swiftlang, which will host critical projects for the Swift ecosystem, including the Swift Compiler foundation (Platforms State of the Union).

Migrate your app to Swift 6
Experience Swift 6 migration in action as we update an existing sample app. Learn how to migrate incrementally, module by module, and how the compiler helps you identify code that’s at risk of data races. Discover different techniques for ensuring clear isolation boundaries and eliminating concurrent access to shared mutable state.
What’s new in Swift
Join us for an update on Swift. We’ll briefly go through a history of Swift over the past decade, and show you how the community has grown through workgroups, expanded the package ecosystem, and increased platform support. We’ll introduce you to a new language mode that achieves data-race safety by default, and a language subset that lets you run Swift on highly constrained systems. We’ll also explore some language updates including noncopyable types, typed throws, and improved C++ interoperability.
