Determine macOS version on which Xcode is running

^ To clarify, I want to check the macOS version in code either via a conditional or at runtime.

So I could be running the iOS simulator but I want to know the host macOS version in which Xcode or simulator is running

How do I check the host macOS version in which Xcode or the Simulator is running?

Why does that matter to you?

@eskimo - I am trying to determine when this scenario exists -

"Simulator now supports remote notifications in iOS 16 when running in macOS 13 on Mac computers with Apple silicon or T2 processors".

from Xcode 14 release notes - (Simulator -> New Features) - https://developer.apple.com/documentation/xcode-release-notes/xcode-14-release-notes

TARGET_OS_SIMULATOR && TARGET_OS_IOS && TARGET_CPU_ARM64

narrows it to AS devices but I can't figure out how to know the sim is running on macOS 13. Also, don't know how to know if it's a T2 Mac.

Oh, good answer.

One options here is to call uname (see its man page). That returns info about the underlying macOS.
