Introduction to WebAssembly for Swift Developers
summary
Swift gains experimental WebAssembly target in upstream snapshots from swift.org and uses embedded Swift to compile modules. The demo uses wasm kit as a Swift package runtime and Hummingbird on the server to load wasm modules, import an audio WASI-like host function, and mix multiple ~100 KB Swift-compiled plugins into a combined audio stream generated on the fly. Examples include a factorial returning a 64-bit result (factorial(10)) and a Hello World that reads linear memory via host imports, and the system runs successfully.
