How to create a Notifications Settings button in the Notification Settings similar to Facebook Notification Settings that will lead users to the app's internal settings page?
To add such a link back to your app from the Settings app -> Notification settings, you would also request authorization for .providesAppNotificationSettings when requesting authorization for notifications.
UNUserNotificationCenter.current().requestAuthorization(options: [.badge, .alert, .sound, .providesAppNotificationSettings])
This will create this button you within the Settings app. When that button is tapped, the system will wake up or launch your app and call the delegate function userNotificationCenter(_:openSettingsFor:) which you need to implement in your UNUserNotificationCenterDelegate
class.
In this delegate function, you can take the steps to navigate to your internal settings view.
