Although the language itself is clearly superior, Cocoa was written for objective c, so coding with this language still is a quite pleasant experience. I don't feel an urge to move to swift right now, but i'll certainly start learning it during the course of the year, and probably switch to it at the end of the year.

The big change will occure once we start to see apple framework designed for swift, using swift specific patterns, and then adapted to objective-c for compatibility purpose. But for now, it's still a wrapper on top.
