XCode 4.1 comes with iOS 4.3 your device is running 4.2.1, thus the SDK does not match. I've you upgrade you iOS on your device to the latest one it should work.

Or when you connect your device the organizer will ask you if it may collect the symbols from your device. If so let it collect the symbols. Then it will know which version your deice is running and it should work.

  • iPhone UUID mismatch detected with the loaded library this kind of warning occurred how to slove this error . – Durga Aug 04 '11 at 07:18
  • The UUID means that the your iOS version does not match any of the installed version on your Mac. You need to upgrade your SDK version. Download an new version of XCode with iOS SDk 4.2 or higher. – rckoenes Aug 04 '11 at 07:26
