Easy way to push and pop UIViewController in swift 5

Step 1 :- Create New file with Name “ExteantionUIViewController.swift”

Step 2 :- Copy and Paste this below extension file

import UIKit

let Application_Delegate = UIApplication.shared.delegate as! AppDelegate

extension UIViewController {

    

    func popVC(_ animation : Bool = true) {

        self.navigationController?.popViewController(animated: animation)

    }

    

    func push(_ viewController : UIViewController, animation : Bool = true) {

        self.navigationController?.pushViewController(viewController, animated: animation)

    }

    func goBackToViewController(ViewController : UIViewController.Type,isAnimated : Bool = true)-> Bool

    {

        var isVCAvalabel = false

        for controller in self.navigationController!.viewControllers as Array

        {

            if controller.isKind(of: ViewController)

            {

                self.navigationController!.popToViewController(controller, animated: isAnimated)

                isVCAvalabel = true

                break

            }

        }

        return isVCAvalabel

    }

   func MackAsRootview(_ viewController : viewController)

    {

            let controller = getVC(on: self.rawValue, viewController)

            Application_Delegate.navigationController = UINavigationController(rootViewController: controller)

            Application_Delegate.navigationController.navigationBar.isHidden = true

            Application_Delegate.navigationController.interactivePopGestureRecognizer!.isEnabled = false;

            Application_Delegate.window!.rootViewController = Application_Delegate.navigationController

            Application_Delegate.window!.makeKeyAndVisible()

            

            Application_Delegate.window!.bringSubviewToFront(Application_Delegate.objCustomTabBar)

            Application_Delegate.objCustomTabBar.isHidden = true

  }
}

    enum myStoryborad : String{

        case Storyborad1 = "Storyborad1”, Storyborad2 = "Storyborad2”

        

        func viewController(_ viewController : viewController)->UIViewController{

            return getVC(on: self.rawValue, viewController)

        }

        func pushVC(_ viewController : viewController, animation : Bool = true) {

            let controller = getVC(on: self.rawValue, viewController)

            Application_Delegate.navigationController.pushViewController(controller, animated: animation)

        }

        

        private func getVC(on storyboradName : String, _ viewController : viewController)->UIViewController {

            let storyborad = UIStoryboard.init(name: storyboradName, bundle: nil)

            return storyborad.instantiateViewController(withIdentifier: viewController.rawValue)

        }

    }

    enum viewController : String{

        case LoginVC = "LoginVC", SignupVC = "SignupVC", ForgotPasswordVC = "ForgotPasswordVC"

        

    }

Step 3 :- Access link

• Push VC :-  

myStoryborad.Storyborad1.pushVC(.LoginVC)

• Push VC with data :- 

let controller = myStoryborad.Storyborad1.viewController(.ForgotPasswordVC) as! ForgotPasswordVC

        controller.dictionary = yourDictionary

        self.push(controller)

• Popup VC :- 

popVC()
