i guess it all comes down to whether you believe swift is going to get better with time and solve its current issues ( the ones you mention),or if it's inherently a bad design. I'm betting on compilation speed and fragility improving a lot in the next two years. What matters to me is that the language type system is among the best ( enums and optionals) , and the general feeling when coding with the language is a real joy.

For objc, however I've never been able to say anything better than "i got used to it".
