I found my answer here. In case anyone else finds this question and needs a solution. Take Xcode out of full screen mode. Still not fixed in 5.2

Xcode 5.0.1 don't show images when you select it in navigation area

A: change your image extension to jpg B: go to ib to your imageview and go to the attributes bar. C: In image: rewrite your image.
