itunes was unable to load data class information from sync services

Question

I recently installed the beta version of xCode, iTunes and the iOS software. I am now getting the above warning in iTunes. xCode doesn't recognize that a phone is connected so I cannot run test apps on my phone.

Any ideas on how to fix this or what went wrong?

Delete the following framework:

/System/Library/PrivateFrameworks/Mobiledevice.framework

.. empty trash, reinstall iTunes 11.
