Issue "Local declaration of 'view' hides instance variable"


I am using the new “Window-based Application” Template (viewtopic.php?f=82&t=3336) with XCode 4.2.1 and iOS 5.

I created the HypnosisView + HypnosisAppDelegate as described in the book. But when I build the project I get the following warning:

The simulator opens and a blank white screen is shown. I get the same type of warnings with the code from other chapters as well. So the reason for this might be a more fundamental misunderstanding.

:bulb: I’d appreciate any “beginner’s” explanation and advice for solving this very much!
