I Don't Know Swift
In the wake of the Swift announcement, it feels like some 'incumbent' iOS developers are saying 'sure learn Swift but if you want to do iOS dev you still need to know Obj-C' (as opposed to 'sure learn Swift but if you to want to do iOS dev you still need to know UIKit' which I agree is obvious) as a strategy to protect their turf.Or perhaps it is just words from the wise?
