Answer 2

I fixed this problem by removing the "Icon already includes gloss and bevel effect" property from the Info.plist file in my project.

Try moving the project to your local hard driver and opening it from there! That solved the issue for me (the project used to be stored on a samba share).

Simply delete the app from the simulator (and/or device if you're attempting to run on your device) via the UI of the simulator, then shut the simulator down and attempt to re-run the app. Doing the deletion of the actual files backing the simulator will also remove the app and do the same thing (but the deletion via the simulator's UI, if it works for you, is a little bit faster and easier).
