Apple seriously needs to add a macOS Simulator to the Xcode toolset, like, yesterday. You should be able to install macOS runtimes just like every other platform, and build and run apps directly from Xcode to any of them. Doing compatibility testing for macOS is a nightmare compared to iOS

@stroughtonsmith For me, this is literally the worst part about writing Mac apps. You can’t install the latest Xcode on older macOS. VMs can’t sign into your AppleID so you can’t build or run the debugger, even if you can build in an older version of Xcode. Every bug on not-the-latest macOS takes 5 times more effort to fix and makes me want to drop our macOS build, entirely.
@cocoawithlove @stroughtonsmith I was hoping for some progress in the virtualization framework on macOS.. still no sign-in possible in a new Sonoma VM?

This part is such an insane limitation. I’m sure there are complicated underlying reasons but… good lord, how does Apple’s own staff even handle it?
