The problem is that you are trying to create a file in your app's bundle. The bundle is read-only in iOS (and you should treat it as read-only on Mac OS as well, even though it is possible to write to your app bundle in Mac OS.)
Your code will work on the simulator because changing the app bundle is allowed on Mac OS, and the simulator runs under Mac OS.
Change your code to use your documents directory, temp directory, or some other directory in your bundle and you should be fine.
