Description

Support for Time-Sensitive notifications on iOS 15+. Time-Sensitive notifications allow the developer to schedule notifications that are important to bypass the Focus active mode or the system Do not disturb settings.

Platform(s)

iOS (15.0+)

Preferred Solution

We should add the new variable interruptionLevel inside the UNMutableNotificationContent. The interruptionLevel variable is an enum with the following values:

case passive = 0
The system adds the notification to the notification list without lighting up the screen or playing a sound.

case active = 1
The system presents the notification immediately, lights up the screen, and can play a sound.

case timeSensitive = 2
The system presents the notification immediately, lights up the screen, and can play a sound, but won’t break through system notification controls.

case critical = 3
The system presents the notification immediately, lights up the screen, and bypasses the mute switch to play a sound.

Maybe add an interface to be exported through capacitor so that developer can get these allowed values.

Also, developer must enable the correct value in App.entitlements for this to work:

<key>com.apple.developer.usernotifications.time-sensitive</key>
<true/>

The above should be added to the documentation too.

When implementing ".criticalAlert" the ".provisional" authorization should be implemented at the same time.
