Answer 1

Add this Protocoal UNUserNotificationCenterDelegate. and add this delegate into your controller. and dont forget to set delegate.

UNUserNotificationCenter.current().delegate = self

func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
        print("Notification being triggered")
        //You can either present alert ,sound or increase badge while the app is in foreground too with ios 10
        //to distinguish between notifications
        if notification.request.identifier == "yourrequestid"{
            completionHandler( [.alert,.sound,.badge])
        }
    }
