Just updated my iphone 13 and now I can't develop on it. I also only have xcode 14.2 and the app store says 14.3 is available but only for macOS 13 or later. Apparently os 13 is not supported on 2015 MBP.
This is absolutely terrible. XCode needs to continue support on os 12 for a good while longer. Even MS has enough sense to slowly let developers catch up for a couple years after a breaking update.
