Problem: currently there's no way to link against ANTLR 4 statically from Swift, which is a deal-breaker if you want to ship a single binary. See cirruslabs/tart#230 for example.
Solution: normally, the
type: .dynamic
should be omitted from library product specification, but changing this now might break things for Swift users. Solve this by introducing a separate Swift PM productAntlr4Static
that explicitly specifiestype: .static
