xcode crashing when opening the assistant editior
Got the new Retina MacBook and it has not been playing nice with xCode. If i make a new project it works, but if i ty triggering the assistant editor it will freeze. If i save a new project and reopen it, it will freeze. I did install the 4.5 DP and uninstalled it and the latest nonbeta version of xcode and the problem still persists. Anyone know what could be the issue? If i make a new user account xcode is behaving normally. Anyone know of a fix? Crash large too large for me to post.

Software Update
If the problem persists go to apple care near by & tell them. There might be any corrupt file in OS X, so go to Apple care and they will guide you to resolve the problem. Currently i'm using same software Mac os 10.7.4 with xcode 4.3.3. I didnt get this problem ever

I experienced similar problems on my Retina MacBook. The workaround is to specify "Open in Low Resolution" for Xcode in the Finder. From http://support.apple.com/kb/HT5266:
This does have an impact on text quality, though it's not awful (subjective). Hopefully Apple will update Xcode soon.
found the same solution, hope its fixed soon

For me, the solution was simple:
Delete the following folders/files from myProject.xcodeproj (or .xcworkspace if you're using cocoapods) (right click on the file and choose “Show Package Contents”)
Reopen Xcode and enjoy
The crash is occurring due to a corruption in project's userdata content.
Also, you should note that after deleting those files, the window size and position will reset and the opened tabs will be all closed.
I am facing the same problem .... I solve it after make changes as per screenshot -

it works for me.
