Common Sense
The first part of the session is a recap of the other notification sessions with some extra common sense such as:
when it is ok for an app to deliver quiet notifications, therefore without prompting the user for the notification authorization and the likes.
Notifications should provide content and value to the user
Notifications are not reasons to open your app (stop.spamming.)
Rich notifications and Apple Watch
Some features of our notifications are automatically translated to an Apple Watch notification for free, for example:
Image attachment
Notification title
Notification body
And quick actions
Ways we can customize the notification:
default:

with customization:

Sash color (the light blue strip on the app name)
Background color (the background blur has customizable tint)
Add in-line images/icons/videos
(New in watchOS 5) Interactive notifications (like iOS 12), available if you have a watch app
