Thanks for the informative listing. So Swift offers refinements (not a paradigm shift like object orientation over functional), many of which could be added to ObjC, and many of which I wouldn’t want. I guess I was trying to find the main, overwhelming purpose driving the adoption of Swift. I think I was looking too high.
