iOS Question

Xcode Organizer: can not use iPhone (dyld_shared_cache_extract_dylibs failed)

When plugging my iPhone in and starting the Xcode organizer, a yellow circle next to the device show me that "This device is busy or otherwise unusable by Xcode."
The Organizer is then processing two files (the second one takes quite a while to finish) and afterwards I get the error message as shown in the screenshot.

I tried to google for that error message ("dyld_shared_cache_extract_dylibs failed") but could not find anything useful.
I tried a couple things: repair permissions of my harddrive and run "sudo update_dyld_shared_cache -force". Still getting the error message.

I am running iOS 4.2.1 and Xcode 3.2.5. I have not updated Xcode after updating from 4.2 to 4.2.1 (I think).

The Xcode console is empty but the regular OS X console shows this:

This error message is then repeated constantly.

Answer

With the help of somebody at the Apple Developer Forums I was able to fix the problem by removing the "/Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.2.1 (8C148)" folder. Xcode then re-added the symbols automatically and the error disappeared. For more information see this thread.
