Swift 6.2 Released

We’re excited to announce Swift 6.2, a release aimed at making every Swift developer more productive, regardless of where or how you write code. From improved tooling and libraries to enhancements in concurrency and performance, Swift 6.2 delivers a broad set of features designed for real-world development at every layer of the software stack.

Swift 6.2 focuses on developer productivity with approachable concurrency features like single-threaded defaults on the main actor, intuitive async functions that run in the caller’s context, and the @concurrent attribute for explicit parallelism.

It advances safe systems programming with InlineArray for stack-allocated fixed-size arrays, Span for safe contiguous memory access, and opt-in strict memory safety to flag unsafe constructs. The VS Code Swift extension gains background indexing, LLDB debugging, a project panel, and live DocC previews for seamless editing.

Swift 6.2 introduces Subprocess for streamlined external process management and enhances Foundation’s NotificationCenter with concrete notification types and async support. Swift Testing adds exit testing, attachments for test results, and raw identifier names, while WebAssembly support enables client/server apps for browsers and runtimes. Migration tooling aids upcoming feature adoption, and the community is thanked for shaping these enhancements.
