I'd argue that it's too late already, the ship has sailed, Swift is heading the same way as C#.

Is there an alternative with similar features and ergonomics? I am def. not aware of one.

For which purpose? It depends what you want to do with it.

Well lang features do not really depend on the purpose the 3d party libs do. Let's say the purpose is web services.

I doubt the web story in swift is that strong anyways, I'd pick python, ruby or php.

I'm having a hard time seeing Swift becoming a well-respected and easily considered language for your next project. The sheer lack of anything outside of what Apple has made already makes it a non starter. In comparison, .Net is absolutely amazing.
