This is one of the known issues in iOS 14, that has not been solved by Apple as of today yet. (almost 4 months old) The problem has not been fixed in iOS 14.0 launch, iOS 14.1 launch or iOS 14.2 launch. Not in 14.3 launch as well.

A workaround is to use iOS 13.x simulator until that issue is fixed (feel free to chime in or call support line to increase the thread’s visibility). Unfortunately, the workaround won’t work if you use iOS 14 features in your app, as it won’t run in iOS 13.x simulators.
