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:
2019-10-08 12:29:08+01 leviathan installd[556]: PackageKit: Install Failed: Error Domain=PKInstallErrorDomain Code=501 "The package is attempting to install content to the system volume." UserInfo={NSLocalizedDescription=The package is attempting to install content to the system volume.} {
Found a solution.
The problem was that when the GM version came out I renamed it
Xcode.app
toXcode 10.app
andXcode beta.app
toXcode.app
App Store couldn't update Xcode then. I had rename
Xcode 10.app
back toXcode.app
and the update worked.Always working workaround (Manual download)

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
Apple suggest this:
