In iOS 11.3 didReceiveNotification function not calling on tap

Question

In iOS 11.3 and above version Mobiles didReceiveNotification function not calling after clicking on notifications. Its working Properly in iOS 9.3 versions.

In my application i wanted to open a different view controller on tap of the application. Based on the notification type.

I am getting the notification its inserting into data base. But after clicking on notification instead of opening required view controller its opening app main screen only.

But in iOS 9 all functionalities are working fine.

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

        let aps = userInfo[AnyHashable("gcm.notification.m")]

        if application.applicationState != .inactive{

        if(aps != nil){
            print(aps)
            self.insertNotification(data: "\(aps)")
         }
        }

        if application.applicationState == .active {

        }

        else if application.applicationState == .background{

        }

        else if application.applicationState == .inactive{

            let array: [Any] = ["\(aps)"]
            self.ns.set(array, forKey: "notify")

            var notification:String = "\(aps)"

            if let range = notification.range(of: "Optional") {
                notification.removeSubrange(range)
            }

            notification = String(notification.dropLast())
            notification = String(notification.dropFirst())

            let json:String = "\(notification)"
            let encodedString : NSData = (json as NSString).data(using: String.Encoding.utf8.rawValue)! as NSData

            do {
                var finalJSON = try JSON(data: encodedString as Data)

                var activityName:String!
                var url:String!
                var serviceUrl = LMUrl()

                if(finalJSON["Notify_Click"].dictionary != nil){
                    activityName = finalJSON["Notify_Click"]["activity_name"].string!
                    url = finalJSON["Notify_Click"]["url"].string!

                    if(activityName == "BuyLeads"){

                        let calWebURL: [String] = ["Buy Leads",serviceUrl.buyLeads+"\(url)&"]
                        ns.set(calWebURL, forKey: "web2")

                        let mainStoryboard: UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
                        let initialViewController:webViewController = mainStoryboard.instantiateViewController(withIdentifier: "WebView") as! webViewController
                        let navi =  UINavigationController.init(rootViewController: initialViewController)
                        self.window?.rootViewController = navi
                        self.window?.makeKeyAndVisible()


                    }

                    else if(activityName == "RC"){
                        let calWebURL: [String] = ["Report Conversion",serviceUrl.reportConversion+"\(url)&"]
                        print(calWebURL)
                        ns.set(calWebURL, forKey: "web")

                        let mainStoryboard: UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
                        let initialViewController:webViewController = mainStoryboard.instantiateViewController(withIdentifier: "WebView") as! webViewController
                        self.window?.rootViewController = initialViewController
                        self.window?.makeKeyAndVisible()
                    }
                    else{
                        print("no Action")
                    }
                }else{
                    let mainStoryboard: UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
                    let initialViewController:notificationsViewController = mainStoryboard.instantiateViewController(withIdentifier: "notificationViewController") as! notificationsViewController
                    self.window?.rootViewController = initialViewController
                    self.window?.makeKeyAndVisible()

                }

            }catch{

            }


        }

        else{
            print("Notification")
        }


        completionHandler(.newData)
    }





    func insertNotification(data:String!){
        let FMDBInfo:Tbl_Info3 = Tbl_Info3()

        let dateFormatter : DateFormatter = DateFormatter()
        dateFormatter.dateFormat = "yyyy-MM-dd HH:mm:ss"
        let date = Date()
        let timestamp = dateFormatter.string(from: date)

        let time = DateFormatter.localizedString(from: NSDate() as Date, dateStyle: .medium, timeStyle: .short)
        //print(timestamp)

        FMDBInfo.notification = data as! String
        FMDBInfo.time = timestamp
        FMDBInfo.time2 = time

        print(FMDBInfo)
