Swift is a language designed from its core to build apps that work well for Apple hardware. I understand why developers gag at its quirky paradigms, but at the end of the day, if you play by the rules, you end up with an extremely valuable product. The positives outweigh the negatives, open source or not.

The problem is that it's actually very unlikely you'll wind up with a valuable product. The odds of getting on a user's home screen get longer every day and if you're not on the home screen you might as well not be on the phone at all.

I would like to see Swift eventually become a general purpose programming language useful outside of Apple's niche but it's got enough baggage from its ties to UIKit & ObjC I'm not sure how likely this is to happen.
