I recently upgraded to the latest version of XCode, but apps made with this new version aren't running on my old iPod. I have the target version set to 4.0, when the iPod is 4.2.1. When I press the run button it goes through the normal building process, says "Running on iPod" then says "Finished running on iPod". But it doesn't run and the app isn't added to the screen. But if I try to run a project made on and older version of XCode it works.

How can I fix this?

You need to add armv6 to the list of valid architectures. Go to your target settings, go to "build settings", search for "valid" to find "Valid Architectures", and change it to have two values, armv6 and armv7.

  • Oh, thanks. I remember checking that, but I guess I was wrong. –  Jun 30 '12 at 05:47
