There was a problem hiding this comment.
IMHO, it would be better to use $(xcrun -f swift) instead of xcrun swift.
xcrun swift is fine with packages that do not contain executableTarget, but it causes the following errors with packages that contain executableTarget:
clang: warning: using sysroot for 'MacOSX' but targeting 'iPhone' [-Wincompatible-sysroot]
To prevent this, you can use $(xcrun -f swift) instead of xcrun swift.

You can easily reproduce this issue by the following steps:
mkdir foo && cd foo
swift package init --type executable --name Foo
xcrun swift build --sdk "$(xcrun --sdk iphoneos --show-sdk-path)" --triple arm64-apple-ios
