I am just guessing here, but let's give it a try:

Have you removed a function that was connected via Interface Builder before or vice versa? Is everything connected correctly? Select your button in the storyboard, open the utility view (it is the right column) and select the connections inspector (circled arrow in the upper right). Are there any connections that should not be there? If yes, remove them by clicking the little x.

Another thing that I noticed is that your action might be missing the parameter sender: UIButton button, not sure if that would trigger a runtime exception, though...
