So, I am trying to learn swift and writing code since about 3 months now. It seems that all of a sudden Xcode won't show the code for the selected UIViewController in the storyboard in the assistant editor. This happens very often. I clean the project - no help. I reset content and settings of the simulator - no help. I create new user on the computer and load up my project there and it works great... For a while. Then we are back to square one. Either I am doing something really weird and messing things up, or the Xcode is doing something really weird and messing me up.

Any quick fixes for this?
