Not to mention with every new release of Xcode, I seem to be immediately unable to build any (or at least many) of my previous projects without much manual tinkering. Jumping through hoops to keep (or retrieve) older SDKs etc. Admittedly I haven't tried this in a year or so, but I imagine the experience hasn't improved. In no other ecosystem have I found existing projects to break so quickly and reliably with every update to my IDE. I would dread Xcode updates for this reason.
