Hi, I have one question regarding communication between the UI Extension and the non-UI/DM extension. If I need to share data between both extensions — for example, an authentication token that will later be used by services called from the DM extension — what would be the recommended approach to do this? Should this be handled through App Groups/shared storage, shared Keychain, or is there another preferred mechanism for Wallet Extensions? Thank you.

Thank you for you answer, but it does not work. The problem is not in the viewcontroller of alertWindow, it is with the below one of mainWindow. This viewcontroller also does not rotate if I set supportedInterfaceOrientations and shouldAutorotate in the viewcontroller of alertWindow. It is like both viewcontrollers share this properties, but I want that one viewcontroller does not allow rotation but the below one yes. Thank you
