WebAssembly Swift SDK selection in Swift 6.2

Platform Swift for WebAssembly
3

I recommend selecting Swift SDKs by their IDs per swift sdk list output and not triple, as both Swift SDKs (embedded and non-embedded) use the same triple. This command would work for any toolchain version, assuming you have jq installed:

 swift build --swift-sdk \
  "$(swiftc -print-target-info | jq -r '.swiftCompilerTag')_wasm"

For Embedded Swift use the corresponding suffix:

 swift build --swift-sdk \
  "$(swiftc -print-target-info | jq -r '.swiftCompilerTag')_wasm-embedded"
