I really hope this is not a permanent implementation of Xcode 15 as many users are still on Monterey and cannot upgrade due to software and/or hardware limitations such as myself. I'm not sure what the intention is other than to force users to use newer hardware as security fixes should always be long-term support and development software should have some compatibility at some level. At this point, I am unable to run use my Xcode 14.1 with my iPhone XR running iOS 17.4.1; sure I can resolve this by downgrading my iPhone to 16.0 versions but that isn't ideal, and upgrading hardware is a hassle in itself. I hope some workaround for this issue comes.
