Swift for WebAssembly
Compile Swift to Wasm and run it in browsers and edge runtimes.
Swift compiles to WebAssembly through the SwiftWasm project, opening the door to running Swift in browsers, serverless edge runtimes, and any host that speaks Wasm. This workstream tracks toolchain releases, browser interop, and binary-size optimisation.
Highlights
- SwiftWasm SDK installation and CI integration
- JavaScriptKit interop and DOM examples
- Strategies for trimming Wasm binary size
From swift.org
WebAssembly is now an officially-supported Swift target. The canonical starting point lives on swift.org:
- Getting Started with Swift and WebAssembly
— installs the Wasm SDK with
swiftly, builds a “hello, world” module, and runs it in a Wasm runtime such aswasmtime. - Swift platform support — the up-to-date list of WebAssembly targets and toolchain releases.
- SwiftWasm — the community project that pioneered Swift on Wasm and continues to maintain JavaScriptKit and related interop libraries.
