Silent Push Notification

Silent push notifications are delivered without an alert message or sound, typically to trigger updates to the app UI or background operations. A silent push notification wakes your app from a “Suspended” or “Not Running” state to update content or run certain background tasks without notifying users.

To use silent push notifications to trigger background tasks, configure your app to receive notifications even when it’s in the background. To do so, navigate to the Signing & Capabilities pane on Xcode, and add the Background Modes capability to the main app target. Also ensure that you select the Remote notifications checkbox.

To handle silent push notifications, implement the application:didReceiveRemoteNotification:fetchCompletionHandler: application delegate method. For more information, see Apple’s documentation on Pushing background updates to your app.
