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 via the App store and there doesn't seem to be an executable with the word "uninstall" in the name anywhere in the Developer folder at all. Any suggestions on how I should go about uninstalling Xcode 4?
This help for Xcode before MAS install /Library/Developer/Shared/uninstall-devtools
If you install it from MAS you can remove from launchpad, but also need to remove some folders** and files created by this app, you can use some helper application that found this files and safely remove it :)
** ex.: ~/Library/Developer, ~/Library/Application Support/Xcode, ~/Library/iPhone Simulator, Logs and etc.
