Uninstall Xcode 4 when it was installed via the App Store

Question

I understand that those who installed Xcode 4 via the developer site are able to uninstall via /Developer/Library/uninstall-devtools –mode=all, however I installed

Answer 1

You must uninstall first the

sudo /Library/Developer/Share/uninstall-devtools –mode=all

It might be something else in your particular case so maybe you can try

locate uninstall-devtools to find where the script is placed.

Then you can find the version you need of xcode from https://developer.apple.com/downloads/index.action

IMPORTANT: If you are going to install a previous version of the Developer Tools, be sure to restart the machine after installing.
