I'm considering adding a language option to cbindgen for Swift.

The Swift compiler lets you include a C header which, when annotated with the CF_SWIFT_NAME macro exposes the C code to Swift code as Swift (so that one doesn't need to for example explicitly pass self/this to functions, similarly as with C++ cbindgen).

Here's more info

Is there any interest in this feature?
