I'm unable to test for iOS but I do have some follow up questions on this PR.

We have a bunch of functionality that is tied to the Alarm ringing / splash screen which essentially decides if the alarm should ring. The preview seems like the app would not be opening, instead, it would display a notification? Please correct me if I'm wrong.

@MarkisDev yes you are true but i will use UNNotificationServiceExtension instead of opening the application again , this provides me to perform custom logic before showing a notification and decide whether to display the notification or not.
