There's a discussion about this on the Apple developer site. They suggest that you put the prior version in the trash before updating. You might want not to empty the trash, just in case.

I have to update a commercial application that's sold on the App Store. I can't do it with XCode 11 - too many horrible bugs. Although it runs I can't edit .xibs to add some UI objects and I doubt that the store would accept an application that logs pages and pages of errors when you use it. I have used Time Machine to get the last version of XCode 10 to get the job done. Apple has really outdone itself in crap with XCode 11. There are many horrible reports about this on the Apple Developer site and other on-line forums.
