Updates between iOS and macOS are independent though if you are developer they are not because iOS and Xcode have to match. In my case my iOS upgraded automatically but my Xcode did not, and could not, because I had postponed the upgrade of my macOS (laziness). After I upgraded my macOS my Xcode could also upgrade to the right version suitable for the iOS version on my iPad and everything worked fine again.
