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

1. may be you have changed the extension of image .jpg to .png like this

2.May be source not available

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.
