My original (unanswered) stack overflow question is here:
I'm now realising that there's probably no way to include the C headers from another Swift package in the C code from a Swift package. I am wondering, however, if there's a way to set up a git dependency or something that would allow me to share Swift code between various packages? Is there any pointers into ways I could achieve this? I'd very much rather not have to duplicate C code across my packages.
