on YouTube ↗36m

" summary

Shows how to compile Swift to WebAssembly using the SwiftWasm toolchain and Carton, interoperate with JavaScript via JavaScriptKit, and run modules in Wasmer or MicroWASI. Demonstrates a reactor vs command model and exporting/importing functions with C calling convention, a multiplayer demo syncing multiple wasm clients with a Vapor websocket back end, and practical notes: GoodNotes reused ~100,000 lines of Swift, binaries hit ~60 MB, and using Swift SDKs and Carton versus manual builds changes workflow and tooling.
