How to handle push notification payload without tapping it when the app is in not running or background state

Question

I have to locally store Title and Body of all the notifications coming in my iOS app and display those in a notifications screen. I'm able to store all the notification tapped by using these-

This gets called when the app is in not running state or killed when the push notification is tapped-

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

This gets called when app is running in foreground or background and push notification is tapped-

    func userNotificationCenter(_ center: UNUserNotificationCenter,
                            didReceive response: UNNotificationResponse,
                            withCompletionHandler completionHandler: @escaping () -> Void) {...}

My question is how to store notifications without tapping on notifications. I want to store the notifications even if the notification is dimissed/cleared by user.

I know this method is called when app is active and in the foreground and push notification comes-

func userNotificationCenter(_ center: UNUserNotificationCenter,
                            willPresent notification: UNNotification,
                            withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {..}

How to handle push notification data without tapping on it when the app is in background or not running state?

AFAIK it is not possible to handle notification when your app is not in a running state - at least if you don't use VOIP. I had a quite similar issue and was wrote a question here (with no success) stackoverflow.com/questions/51055491/… — Teetz
@Teetz Is there a way to handle the notifications data when the user opens the app next time? — kumarsiddharth123
I am not 100% sure but i don't think so. AFAIK apps that do that are storing their push notifications on their backend-server and ask the backend at app start to get all the remote notification data. — Teetz

1- If the app isn't running then no way to wake up the app only with ( VOIP )

2- if in background then add this key to the sended payload

"content_available": true

And enable RemoteNotifications from app capabilities
