Resolved Xcode hangs on launch

    Some time ago I downloaded and ran successfully Xcode 4.3.3 and Xcode 4.4 simultaneously. Then, troubleshooting I deleted them, wiping out all files referencing to both Xcode versions through Terminal. I then re-downloaded 4.3.3 and was able to launch and run it, however 4.4 which I re-downloaded afterwards refused to do the same resulting in an endless hang which to abort I could only resort to Force Quit. Having launched again I was greeted with a notification message suggesting me to either to restore previous windows or do not restore. Regardless of the option selected the hang renewed immediately until the next ForceQuit etc. I can't understand what went wrong this time? I haven't started any projects that could become corrupted or so as a common explanation suggested on numerous forums. I remember that since Apple's certificate expired and being on Lion I needed older versions of Xcode I changed the date to the one closer to the original release date. The first time trick worked with both version (although I can't remember how exactly I changed them) and so it did with 4.3.3 this time but not with 4.4.

    Also, if it might seem useful, when uninstalling I removed these binary files referencing to Xcode:






    I removed these items because I thought it was bundled with Xcode and therefore would be re-installed again. Was I wrong? Was these built-in OS X?

    Acting on intuition I looked inside packages of both versions but could only find /usr/bin/xcodebuild.

    So what should I do?

    No doubt the fastest solution would be reinstalling, either from backups or with original installers, of either or both Xcode and/or OSX. If you actually want to know what's going on though maybe try truss on Xcode, or sampling it, to see what its waiting for.

    I solved. It turned out my instinct didn't do a bad turn as I later learned that the binaries in /usr/bin and /usr/share were responsible for launching several versions of Xcode. I downloaded Lion combo update from Apple's downloads section, installed these components using Pacifist and the problem was gone.
