If we have Swift interworking we can also do the inverse: support Apple’s Swift 
compiler with our own C and Objective-C based libobjc2, CoreFoundation and 
Foundation packages. This way instead of throwing out chunks of the code we 
have to extend and adapt them to fit the Swift compiler. This will require us 
submit some patches to Apple though to enable building of the macOS Swift 
interworking code on the Linux version.
