You might want to install it as something other than Xcode.app, like Xcode.10.3.app; you should be able to use xcode-select to pick which one has its command-line tools used. There's another package there for the command line tools, too, I think. Maybe someone else can better explain how to set it up so you can properly have what you need, without interfering with what you've already updated via the app store.
