I can't seem to get the workaround to work because of the static linkage.
My setup is:
- A (XCFramework)
- A depends on B (Swift package I have control over)
- B depends on C (Apple package, no linkage specify, Xcode defaults to static)
XCFramework seems to look for dependencies using dyld (dynamically). I can change my package B to be a dynamic library, then iOS is able to find it. But I can't enforce dynamic linkage for C. Any suggestions?
Update: Apparently Apple says in WWDC 2019 that binary frameworks cannot depend on Swift packages. I'm not sure that's fully true because my experiment with dynamic library proved to work. Anyway, I managed to get this to partially work by rewriting the frameworks so that B doesn't depend on C. I now have A -> BCore and B -> BCore, C. Both A and BCore are now binary frameworks as Apple intended.
