For Foundation, we create a static library for the C portion of (this is CoreFoundation), then link it with the resulting dylib created from the Swift portion. The idea was that no one should use the C stuff directly. I’m not sure if this will work for dispatch - I haven’t tried it myself. We’re in very new territory here so I think we’ll have to experiment with a few things and see what works. I expect to find issues in clang’s support for this.
