iOS: using NotificationServiceExtension

For iOS, the app must use NotificationServiceExtension to process notifications in the background.

Implementation steps

1. Integrate NotificationServiceExtension

Add NotificationServiceExtension to your iOS project. This extension allows your app to process the incoming push notification data in the background before presenting it to the user.

2. Wake-up the app

When a push notification is received, the NotificationServiceExtension will be triggered, waking up the app.

3. Connect with Breez SDK

In the extension, establish a connection with the Breez SDK to process the incoming payment.

4. Wait for payment completion

Once connected, the app should wait for completion status from the Breez SDK that the payment has been received.

5. Display a notification

After confirming the payment, display a notification.
