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.

Tried reinstalling 4.3 but it's not giving me the option again. Also, Instruments is not showing me targets anymore. – Woolworth

Couldn't wait any longer. Just did it manually. Removed Xcode 4.3 by deleting the app folder in Applications then ran this command. 'sudo /Developer/Library/uninstall-devtools --mode=all' Afterwards just reinstalled 4.3 again for a clean fresh install. – Woolworth

did that work, did it let you uninstall the prior installation of xcode like the first time? – Capper

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

Great info; thanks! One additional note: when I opened ~/Library/Preferences/com.apple.dt.Xcode.plist, it opened in Xcode 4.2. I was a little concerned about making the change with any version of Xcode open, but it worked anyway. I made the changes using Xcode 4.2, saved, quit Xcode 4.2, started Xcode 4.3 and everything was as desired. – Judaic

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.
