How to uninstall xcode3 from Lion 10.7?

I have just bought a macbook air 11" with Lion 10.7. I installed xcode 3.2.5 on it. But its not working. Xcode is installed, consuming much space but I cannot see it in applications. Somewhere I heard that xcode 3 will not work on Lion 10.7, only xcode 4 is compatible on this os. Is it really true? I tried removing xcode 3 but efforts go worth开发者_Python百科less. What should I do to uninstall it?

For Xcode, you want to use scripts provided with Xcode to remove it completely. Open a terminal window and invoke /Developer/Library/uninstall-devtools. Alternatively, you can just drag the Developer folder to the trash, but I don't think that removes everything that gets installed by the installer.

And no, Xcode3.2 won't work (entirely right) under Lion. You need Xcode4, v4.2 being the most recent with the iOS5 SDK. And if you want to submit anything to Apple, you'll need 4.2 (i.e. the latest released tools) anyway, at this point.

I would use this utility. It's always worked better than the traditional way to "unistall" applications form OSX

The reviews have always been good for this app.
