on xcode 11 you can see what settings you already have like this:
defaults read com.apple.dt.xcodebuild
defaults read com.apple.dt.Xcode
this is what i use:
defaults write com.apple.dt.xcodebuild PBXNumberOfParallelBuildSubtasks `sysctl -n hw.ncpu`
defaults write com.apple.dt.xcodebuild IDEBuildOperationMaxNumberOfConcurrentCompileTasks `sysctl -n hw.ncpu`
defaults write com.apple.dt.Xcode PBXNumberOfParallelBuildSubtasks `sysctl -n hw.ncpu`
defaults write com.apple.dt.Xcode IDEBuildOperationMaxNumberOfConcurrentCompileTasks `sysctl -n hw.ncpu`
The above also works on Xcode 14
