I've installed the XCode 4.3. I've seen that in preferences general tab, there is the "iOS device discovery" tab. Maybe it was there before too, but I just noticed now. So I've checked it, after this I can do anything, but the XCode crashes constantly when I try to access the organizer's devices tab.
Any clues for solution?
Update: I've deleted it and reinstalled it from the Mac App Store, but it didn't help
Update: I've submitted the bug to Apple, they marked it as duplicate and after this they closed both of them. So, I hope we will have a solution from Apple.
Same Problem here. I just created a new user on my system. With it I have no problem open the Devices in the Organizer Window.... strange...
Edit: I've deleted one certificate in my keychain that solve the problem for me. It was a certificate which was not trustful. Maybe this will help you.
Note that the "harmful" certificate might not be a development certificate or related to development/provisioning at all. Make sure to check for "Certificates", not just "My certificates" in Keychain. The culprit could be any certificate, like a company-signed SSL certificate etc.
