Swift is definitely interesting, but I wish they hadn't tied themselves so much to ObjectiveC and how the framework works. The most obvious area where this shows is that Swift doesn't have exceptions or any other form of built in error handling.

(though CocoaTouch proves you can slap a very different language on top of the Cocoa and do thing that don't exactly fit with ObjC)
