There are ways to still maintain API compatibility in that case (Windows does it all the time), and it’s also not a reason to require projects not affected by those changes to recompile with the newest Xcode version each year. I’m maintaining a Swift library/framework that doesn’t use any iOS APIs at all, only basic Swift standard library calls, and I still have to produce a new build each year from unchanged source code so that the library can be consumed with the new Xcode version. That’s just insane.
