Hi-

Your fetch request isn't finding any Categories, and the array returning from executeFetchRequest is empty. Before doing the setValue:forKey:, you should test the returned array from executeFetchRequest to make sure it contains >0 categories, and handle the situation appropriately if it doesn't. You should also, by-the- by, be passing an NSError pointer to executeFetchRequest: and testing that after it returns to make sure an error didn't occur.
