I was having problems with XCode referring to a View Controller I had just deleted and it turned out the linker was loading stuff from cache.
I found this stack overflow question and deleting the contents of this folder solved the issue:
~/Library/Application Support/iPhone Simulator/4.3.2/Applications
Now I can continue learning :D
