Command SwiftCompile failed with a nonzero exit code

[alanhamlett]

Getting this error when building the project after upgrading Xcode to v15.4. Tried deleting DerivedData folder and still occurs. Not sure how to get a better error message, that's the only error I'm finding.

Running swift build -v shows more info but still not helpful. Looks like a bug in Swift compiler:

Downgraded Xcode to 15.2 and it builds ok.
