You need to update XCode to the latest build (4.4).

I've come across the same thing, and went to the Mac App Store and downloaded and installed Xcode through that.

However, it seems to have put the new Xcode.app straight into the Applications folder, whereas before (v 4.2.1) was installed in Developer\Applications\Xcode.app. In fact, it still is!

How do I uninstall everything that belongs to Xcode 4.2.1 from my system, but leaving Xcode 4.4. It seems parts of the new Xcode (4.4) have been put into the \Developer\ folder as well, so it's not obvious what I would need to delete... Can anyone shed some light on this?
