OSes (MacOS, iOS, watchOS, tvOS) and Xcode get released in lockstep. The SDKs for each year’s OS releases will work only on that year’s Xcode, which runs on no earlier than the previous year’s MacOS. I’ve been able to transplant the SDK for iOS 13 (which requires MacOS 10.14) so that I can develop on MacOS 10.13 (the latest my MacBook Pro will run), but that’s about to run out. I may end up with a cheap dev-only Mac Mini.
