Not having to emulate iOS apps on macOS will be a boon for Xcode developers.

I doubt iOS devs are very high up on the list of parties to please with this move

iOS apps do not run via emulation on macOS; they are compiled for x86_64 and run as a normal process.

And it’s actually a pre that every iOS app works on multiple architectures. If Apple ever wants to change iOS to run on a different type of CPU it’ll be easy.

And they've already made advantage of that, with the move from A32 to A64.
