Apple is rewriting Foundation in Swift
I just... completely don't understand the appeal of Swift beyond it being Apple's in-house language.  I was excited for Foundation to become open-source.  Using a language you'll really only find in 1 environment is a negative.  I'm going to go feel ashamed for not getting excited about a language now.  I should be celebrating "more languages", but Swift is just Apple.  No one outside Apple chooses Shift unless they want to build something in Apple's ecosystem.
