I don't understand why we have to wait nearly a month for Apple to issue an emergency fix for Xcode such that the latest release of Xcode will build for the latest iOS and iPadOS, nor do I understand how Xcode version 11.3 passed testing and got released, given that it doesn't build for iOS 13.3. I would have thought Apple has the highest quality standards in testing its products. Until this is put right, I have no option but switch auto-update to OFF and manually manage all Apple upgrades.
