This wasn't super clear to me, I think that you should lead with the fact that there are two ways Swift can support interop:
- by having the compiler emit a header file that contains C declarations for Swift symbols
- by implementing functions that are declared in a user-written header
and that @cdecl/@objc are for the former and @implementation for the latter.

Good idea, I changed the paragraph structure to hopefully make the alternatives clearer.
