Schedule Local notification on Remote Notification

Question

In our project, we want to changed a title and body of Remote Notification . In that we generate a Local Notification and Display a local notification with changed a title and body and hide push Notification. But in that while App is in Background and kill State it will display a Remote a Notification instead of Local Notification. But we want to display a Local Notification instead of push in Will present Notification. how to do this ?

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

        if notification.request.identifier != "local_notification1"{
                self.isAdded = false
        }
            let name = (ContactsManager.shared.getContacName(withPhoneNumber:notification.request.content.title) != nil) ? ContactsManager.shared.getContacName(withPhoneNumber:notification.request.content.title) :
                notification.request.content.title
            let notificationContent = UNMutableNotificationContent()
            //        notificationContent.userInfo = notification.request.content.userInfo
            notificationContent.body = notification.request.content.body
            notificationContent.title = name!
            debugPrint("name title is %@ ", name)
            debugPrint("notificationContent title is %@ ", notificationContent.title)
            notificationContent.sound = .default

            let notificationTrigger = UNTimeIntervalNotificationTrigger(timeInterval: 0.1, repeats: false)
            let notificationRequest = UNNotificationRequest(identifier: "local_notification1", content: notificationContent, trigger: notificationTrigger)

            if !isAdded {
                UNUserNotificationCenter.current().add(notificationRequest) { (error) in
                    if let error = error {
                        debugPrint("Unable to Add Notification Request (\(error), \(error.localizedDescription))")
                    }else {
                        print("is Shown")
                    }
                    self.isAdded = true
                }
                 completionHandler([])

            }
         completionHandler([.alert,.sound])
   }    
}
