I hate Storyboards - I can't even come close to manipulating views/subviews the way I want to with them.

I love dot syntax. Writing myArray.count is a lot easier than [myArray count] and then when messages start getting nested it bothers me visually - ie [[myView subviews] count]. Of course, I love messages and the syntax used for calling functions too.

Objective-C is my first real language though, so what do I know.
