With macOS 13, simulators are handled separately from Xcode. So it's possible to have a newer simulator available that's not compatible with the selected version of Xcode.
For example, iOS 17 can be available even if Xcode 14 is selected.
So when you do xcrun simctl list runtimes, iOS 17 will be listed.
This is potential problem because we use the greatest runtime from xcrun simctl list runtimes to create a simulator and run tests on it.

For Xcode 14, we want an iOS 16 simulator to be used, not iOS 17.
