Worked on the swiftlang/swift-build repository to deliver a Swift SDK supporting WebAssembly (WASM) workflows, enabling clients to synthesize a Swift Build SDK by specifying manifest paths and target triples. The implementation involved hardcoding WASM platform paths and enhancing the SDK registry to generate SDKs from run destination information, improving reliability for WASM SDK provisioning. Refactored the SWBBuildTarget API from an enum to a struct, increasing clarity and extensibility for multi-platform support. Integrated comprehensive test coverage for WASM SDK handling and aligned build scripts to WASM requirements, leveraging Swift programming, SDK development, and WebAssembly expertise throughout the process.
