Still occurs in iOS 15.2 simulator, seems to work on physical device.

I'm testing some of the app group functionality at the moment and can confirm UserDefault.standard isn't affected by the extension. Simply put, only the app can access UserDefault.standard. Happy to open a new thread, but what would you recommend to move files from FileManager.default.urls to FileManager.default.containerURL to support data sharing between the app and extension. In particular, what's the best function to handle the update when a user downloads the latest version of an app. Appreciate any guidance 😃

Thanks for the reply. I assume the UserDefault.standard accessible by the app aren't affected given SSO extensions are configured as of part of an MDM infrastructure

I was seeing a different error initially as reported here: https://developer.apple.com/forums/thread/691213 When I removed kSecAttrAccessible as String: kSecAttrAccessibleAfterFirstUnlock I then was able to confirm this behaviour is also occurs in iOS 15 simulator with Xcode 13.

On first launch, HasAchnowledgedUserLicence returns false as there is no key for it in UserDefaults and navigates to the UserLicenceViewController where some text is displayed for the user to agree to. The user tap "Agree" which sets HasAchnowledgedUserLicence to true then _ = navigationController?.popToRootViewController(animated: false) is invoked, where the condition is now met and the WelcomeViewController is shown.
