ios – Notification delegate not being referred to as when app is in background when notification is acquired

I’m utilizing firebase cloud messaging to ship push notifications to our iOS software. When the applying is within the foreground all the pieces works positive.

The issue is when i ship the app to the background after which ship a notification.

I anticipate the next delegate to be referred to as, however it isn’t:

func software(_ software: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any],fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult)-> Void) {

I’ve ticked the “distant notifications” background mode in my apps signing & capabilities tab.

The payload i ship to firebase appears like this:

{"to":"--TOKEN--",
"precedence":"excessive",
"content_available":true,
"mutable_content": true,
"notification":
 {"physique":"Take a look at Notification",
 "title":"New Notification",
 "sound":"default",
 "click_action":"notification"
 }
}

This payload is shipped to firebase through https://fcm.googleapis.com/fcm/ship

When i click on an notification it’s then processed, and that i can see the apns model i obtain appears like this:

[AnyHashable("google.c.sender.id"): 8xxxxxxxx, AnyHashable("gcm.message_id"): 1xxxxxxxxxx, AnyHashable("google.c.a.e"): 1, AnyHashable("google.c.fid"): fxxxxxxxxx, AnyHashable("aps"): {
    alert =     {
        body = "Test Notification";
        title = "New Notification";
    };
    category = feedback;
    "content-available" = 1;
    "mutable-content" = 1;
    sound = default;
}]

I’m not certain why content-available and mutable-content seem in quotes? I do know firebase convers its payload to apns format, is there one thing fallacious right here?

I need the delegate to be referred to as in order that i can execute some code to keep up varied information gadgets, so it is vital that i can run some code when my app is within the background and a notification is acquired.

I’m not certain what config i’m lacking as all the pieces i learn appears to say that is all i must do?
