Trying to update from Xcode 11 GM to 11.1 always fail.

I tried moving /Applications/Xcode.app first... nothing works

This is my commerce log:

Always working workaround (Manual download)

Download directly from Apple:

Latest Release version

or

Latest Beta version

or

Any version you need. And all other downloadable contents

Then extract and move it where you like. This has so many benefits comparing to appstore update. (like the ability to resume download, not replacing the old one, not wasting hidden directories and etc.)

Note that you should use safari to download it.

Apple suggested workaround (Force App Store to redownload)

Since This is Known Issues

Xcode may fail to update from the Mac App Store after updating to macOS Catalina. (56061273)

Apple suggest this:

To trigger a new download you can delete the existing Xcode.app or temporarily change the file extension so it is no longer visible to the App Store.

Found a solution.

The problem was that when the GM version came out I renamed it Xcode.app to Xcode 10.app and Xcode beta.app to Xcode.app

App Store couldn't update Xcode then. I had rename Xcode 10.app back to Xcode.app and the update worked.
