- **Explanation**: Renames the WebAssembly target triple from `wasm32-unknown-wasi` to `wasm32-unknown-wasip1` to align with the broader WebAssembly ecosystem's naming conventions. It's important to include this in 6.2, which is going to be the first stable release of Swift SDK for Wasm, so that we won't introduce a breaking triple change in the stable version series later. The WebAssembly ecosystem has been migrating from the generic wasi target name to more explicit version-specific names like `wasip1` and `wasip2`. This change has been adopted across multiple toolchains and language ecosystems: - Rust: Renamed `wasm32-wasi` to `wasm32-wasip1` (https://github.com/rust-lang/compiler-team/issues/607) - wasi-sdk: Renamed `wasm32-wasi` to `wasm32-wasip1` (https://github.com/WebAssembly/wasi-sdk/pull/386) - Go: Already uses `wasip1` naming convention (https://github.com/golang/go/issues/58141) The "p1" suffix explicitly indicates WASI Preview 1, which helps distinguish it from the newer WASI Preview 2 (wasip2) and provides clarity about which version of the WASI specification is being targeted. Also we already use `wasm32-unknown-wasip1` for Embedded WASI target, and having different names for Embedded and non-Embedded is confusing users. - **Scope**: Narrow, only affects Wasm Swift SDK. - **Original PRs**: https://github.com/swiftlang/swift/pull/83167 - **Risk**: Low, just a change to Wasm Swift SDK - **Testing**: CI. - **Reviewers**: @MaxDesiatov
