Uninstalling Xcode Developer Tools

To uninstall Xcode developer tools on the boot volume along with the <Xcode> directory, from a Terminal window type:

$ sudo <Xcode>/Library/uninstall-devtools --mode=all

To remove the underlying developer content on the boot volume, but leave the <Xcode> directory and supporting files untouched, from a Terminal window type:

$ sudo <Xcode>/Library/uninstall-devtools --mode=systemsupport

To just remove the UNIX development support on the boot volume, but leave the <Xcode> directory and supporting files untouched, from a Terminal window type:

$ sudo <Xcode>/Library/uninstall-devtools --mode=unixdev

Finally, to just uninstall the <Xcode> directory you can simply drag it to the trash, or from a Terminal window type:

$ sudo <Xcode>/Library/uninstall-devtools --mode=xcodedir
