Xcode 4.6.3 crashing after installing xcode 6 beta

Question

I've installed Xcode 6 beta for tryout, and older 4.6.3 now crashing on start, I need it to work on enterprise app. Already tried to reinstall 4.6.3, removed 6, nothing helps. Is there any decision for that kind of problem?

Try this:

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