It does look like this is a known bug (not yet fixed) in SPM: https://bugs.swift.org/browse/SR-3280 <https://bugs.swift.org/browse/SR-3280>
The bug isn’t fixed yet (apparently it’s blocked on a swift compiler issue.) There’s a workaround in that report, though I don’t know how viable it is. Anyway, you can track that bug to see when this gets fixed.
