Facing Issue with Reachability IOS Swift

Question

I Created Reachability in one Demo project in that project i have two view controllers if internet connection is there i am displaying OnlineViewController if internet connection is not there I am displaying OfflineViewController. See the following Code which i have implemented in Appdelegate.swift.

 var reachability:Reachability?
    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {

        NotificationCenter.default.addObserver(self, selector: #selector(reachabilityStatusChanged(_:)), name: .reachabilityChanged, object: nil)
        reachability = Reachability.forInternetConnection()
        reachability!.startNotifier()
            return true
    }

And My function is like This

 @objc func reachabilityStatusChanged(_ sender: NSNotification) {

        var remoteHostStatus = self.reachability!.currentReachabilityStatus()

        if (remoteHostStatus == NotReachable)
        {
            print ("no net")
            let testController = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "OfflineViewController") as! OfflineViewController
            window!.rootViewController = testController
            window!.makeKeyAndVisible()
        }
        else
        {
            let testController = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "OnlineViewController") as! OnlineViewController
            window!.rootViewController = testController
            window!.makeKeyAndVisible()
            print (" wifi")

        }

    }

Now my question is i want to implement same thing in my realtime project in that project i have 3 storyboards and mutiple viewcontrollers. so how to display user current screen again if internet connection is there.

Answer 1

I resolved my issue with following code. i am not sure whether my answer is right or wrong.

@objc func reachabilityStatusChanged(_ sender: NSNotification) {

        var remoteHostStatus = self.reachability!.currentReachabilityStatus()

        if (remoteHostStatus == NotReachable)
        {
            print ("no net")
            let testController = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "OfflineViewController") as! OfflineViewController
            window!.rootViewController = testController
            window!.makeKeyAndVisible()
        }
        else
        {
          UserTypeValidateCall()

        }

    }.

//MARK:- Validating User Type
func  UserTypeValidateCall()
{
    let Usertype  =  UserDefaults.standard.string(forKey: "Usertype")
    print("Usertype-----",Usertype)

    if(( Usertype) != nil)
    {
        if (Usertype?.isEqual("Parent"))!
        {
            ParentDashBoardEnter()
        }
        else  if (Usertype?.isEqual("Employee"))!
        {
            TeacherDashBoardEnter()
        }
        else if (Usertype?.isEqual("Admin"))!
        {
            AdminDashBoardEnter()
        }
    }
    else
    {
        LoginScreenEnter()
    }
}
