I've just started getting into Cocoa dev after doing iOS for a while and it has more than its own share of warts. KVO is a clunky API that's very inconsistently available and easy to misuse. Interfaces built using auto layout in xibs are very tricky to debug and maintain. There's all kinds of string typing in the APIs which defeats many of the benefits of static typing. And there seem to be a lot of quirks and bugs in the API overall which I'm guessing are a result of Apple shifting its focus to iOS, where the money is. All in all I'll take the web stack, particularly with the changes coming down the pipe. Javascript with ES6 is a much better language. And if web components really take off then component-based UI development on the web will be pretty competitive with Cocoa.
