Because it's actually a well designed language that's productive and modern?

In my opinion the only thing missing is better reflection (will get better), concurrency a la Go (they're considering), and async/await. There are a couple unfinished bits but the compiler tells you "X feature not implemented YET"

What's wrong with it?

i strongly disagree with that sentiment. but there we go... i can certainly go into more detail if you would like, but the main thing for me is that it solves no problems that existing languages do not, and the generated code (i.e. instructions for the CPU) from using the abstractions provided are considerably worse for performance than if i abuse a language like C++ to achieve the same features.

this is damning of the quality of the compiler imo. now that its open source i might make some effort to help this... but it seems unlikely given the utter lack of motivation to use the language to begin with (a tiny thing layer of obj-c is all i need for now - i see no reason to change this - even in light of swift)

to me it seems like apple are solving a problem that doesn't exist because they choose to ignore established and well developed languages and tool chains.
