Lion, Xcode 4.3.3, and vex code 4.5 dp4
After creating a new local git branch to specifically avoid this type of problem, I’m unable to open a critical production workspace with xcode 4.3.3 after having opened it, in another branch, with xcode 4.5pd4. I also tried cloning from origin again, as I haven’t pushed to remote since opening the workspace in 4.5, but I’m unable to open that version of the workspace either. No matter what I do, Xcode 4.3.3 crashes soon after launching. What can I do to reset, delete preferences, whatever, to get 4.3.3 working again?

I had to have inadvertently opened the workspace on the incorrect branch at one point; it’s the only thing that makes sense. I noticed that after opening it under 4.5 again, all my xib’s were defaulted to an incorrect compatibility in IB, and after manually adjusting them all to proper values using the current tools versions and making sure none were set to use a new, feature (that I’m not naming here due to NDA purposes) I was once again able to open the workspace under both 4.3.3 and 4.4.
