App Store Xcode Updates

[tpitman]

I have Xcodes installed and want to use it exclusively for updating Xcode.

I seem to still be getting the updates from Apple when there is a new version.

Could this be because that update was already available before I installed Xcodes?

What should I do if I have already installed a new version of Xcode and then see the Apple notification that there is an update for the same version?
