In Xcode 13, using the 14.5 and 15.0 simulators, when I use UserDefaults to save preferences for the user, the defaults seem to go away when the app quits (I am using the home button / app switcher / slide up gesture to quit the app in the simulator). This problem does not occur when using my actual devices (iPad and iPhone). [userDefaults synchronize] returns YES, however I am getting nil for the key I saved upon next launch. Note: I am using NSKeyedArchiver archivedDataWithRootObject with requiresSecureCoding set to YES for some keys, however the first key is not using NSKeyedArchiver and is also returning nil.
