[swift-evolution] [swift-corelibs-dev] Proposal: Swift Open Source Project and Foundation replacements

Could you point out five Objective-C Linux libraries (apart from GNU Foundation) that you'd like to use in your Swift projects on Linux? I suspect you can't and that's why I strongly disagree. You only need Objective-C on Apple platforms – and that's not going away. 

Maintaining Objective-C interoperability for non-Apple platforms is a very niche aim and could potentially lead to longer development and evolvement process. That's a reasonable tradeoff.

During early days (2002) lots of components in C# are stubs calling back to MFC but nevertheless this presented a more or less complete library set to the user and allowed the language to gain traction - so many traction that now people demand it to be ported to multiple platforms.
