XCode 4.3 - Uninstall XCode 4.2

Question

Initially launching XCode 4.3, I was given an option to uninstall Xcode 4.2. I didn't uninstall the first time and I'm having trouble locating that option within Xcode 4.3. How do I find this option again?

Instead of doing the uninstall manually, I would like to use what Apple recommends so please no answers on doing it any other way. Thanks.

Answer 1

Hi I found a solution to gain the option again:

1. Close Xcode
2. Go to ~/Library/Preferences
3. Open com.apple.dt.Xcode.plist
4. Search IDEHaveOfferedXcodesToRemove and set the Boolean value to false
5. Save & close
6. Now open the Xcode 4.3 again and the option will become active again

Answer 2

Per the Xcode 4.3 release notes:

If you choose not to delete these items on the first launch of Xcode 4.3, you can remove the /Developer folder and the Install Xcode application by dragging them to the Trash at any time.

(Whew!)
