4.21 & 4.22 only support Xcode 10.x, switch to 4.23 with Xcode 11 or have a another copy of Xcode 10 if working on 4.21/4.22

You can install an older version of Xcode and keep the current.
To select which XCode should be used by unreal, open macOS terminal and use this command:

sudo xcode-select -switch PathToYourDesiredXCodeVersion

for example:
Make a subfolder in /Applications for the older version, named /Applications/XCode10/
then you can switch which one, using one of these command:

sudo xcode-select -switch /Applications/Xcode.app
sudo xcode-select -switch /Applications/XCode10/Xcode.app
