How to Uninstall Xcode
A friend in San Francisco, Rodney Aiglstorfer, was recently jumping through hoops to get Xcode to cooperate with his iPhone. There’s nothing more aggravating than having your application running within the simulator and getting stuck downloading to a device.
At one point in the process he opted to remove the Xcode developer tools and start the configuration from the beginning. Which leads to the tip: should you ever find the need to remove Xcode, run the following from within a terminal window to make it happen:
sudo <Xcode>/Library/uninstall-devtools --mode=all
<Xcode> is the directory where the tools are installed. For typical installations the full path is /Developer/Library/uninstall-devtools
Easy enough, just make sure this is what you really intend to do as once it’s gone, it’s gone.
