问题
I updated Mavericks 10.9.2 to 10.9.3 and downloaded Xcode 6 beta. One of my project is still in Xcode 4.6.3. So now whenever I open this project Xcode crashes with the following pop up.
It was working fine in OS X 10.9.2. Is it OS related issue? Please help
回答1:
I had similar issue. This can be fixed using
`sudo mv /System/Library/PrivateFrameworks/MobileDevice.framework{,-saved}`
This will ask for system component installation and then Xcode starts working.
I recommend to use latest version of Xcode 6.x.

Try this:
sudo mv /System/Library/PrivateFrameworks/MobileDevice.framework{,-saved}

Javi Campana's answer and Iron Eagle's ( Xcode 4.6.3 crashing after installing xcode 6 beta ) worked for me.
I believe the missing key point is running Xcode 4.6.3 directly after renaming the MobileDevice.framework.
Xcode 4.6 will then prompt you to install "Device Support" component.
Once installed, my Xcode 4.6.3 and Xcode 6 beta 2 worked again with MobileDevice.framework version 555.43 created Dec 21, 2014.

So it turns out Xcode 4.6 does not work with iTunes higher than 11.4.
