There is no interception possible for remote notifications.

But the thing you want to do is possible like:

• You modify the notification payload to be a silent push notification
• You opt-in the Remote Notifications in background modes of your app's capabilities
• Then use local notifications. When you receive a remote notification from your server, you will be able to decide to show or not any local notifications.

Footnote: In this approach, if the user has killed the app by swiping it up in the fast app switching mode, you won't be able to get any callbacks for your app in background when you receive a remote notification.
