Swift 6.2 has been released with WebAssembly support, a new Subprocess package, and single-threaded-by-default concurrency mode. The release expands Swift's reach beyond Apple platforms while making concurrent programming more accessible.

WebAssembly Compilation

Swift 6.2 gains support for WebAssembly, enabling developers to build both client and server applications for the Wasm platform. This opens Swift to web development and edge computing scenarios previously inaccessible to the language.

Subprocess Package

The new Subprocess package provides a streamlined, concurrency-friendly API for launching and managing external processes. This addresses a long-standing need for robust process management in Swift scripts, automation tools, and server applications.

Single-Threaded by Default

Swift 6.2 lowers the barrier to concurrent programming with single-threaded-by-default mode. Code runs on the main thread without explicit @MainActor annotations, simplifying the migration path for existing codebases while maintaining the option for explicit concurrency when needed.

Ecosystem Expansion

The swift-java interoperability project now allows bringing Swift into Java code. Apple's Containerization project enables running Linux containers on Mac using Swift. Android development progresses with daily snapshot builds, and Windows support matures via the VS Code extension.
