Swift SFSafariViewController представляет пустую страницу

EDIT2, здесь MW C, содержащий 2 класса с только SFSafariViewController для открытия встроенного URL-адреса. На экране отображается пустая страница. Файлы также находятся здесь https://github.com/camillegallet/testSwiftSafariEmbeded

AppDelegate 

import UIKit

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

    var window: UIWindow?

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
        // Override point for customization after application launch.
        return true
    }



    func applicationWillResignActive(_ application: UIApplication) {
        // Sent when the application is about to move from active to inactive state. This can occur for certain types of temporary interruptions (such as an incoming phone call or SMS message) or when the user quits the application and it begins the transition to the background state.
        // Use this method to pause ongoing tasks, disable timers, and invalidate graphics rendering callbacks. Games should use this method to pause the game.
    }

    func applicationDidEnterBackground(_ application: UIApplication) {
        // Use this method to release shared resources, save user data, invalidate timers, and store enough application state information to restore your application to its current state in case it is terminated later.
        // If your application supports background execution, this method is called instead of applicationWillTerminate: when the user quits.
    }

    func applicationWillEnterForeground(_ application: UIApplication) {
        // Called as part of the transition from the background to the active state; here you can undo many of the changes made on entering the background.
    }

    func applicationDidBecomeActive(_ application: UIApplication) {
        // Restart any tasks that were paused (or not yet started) while the application was inactive. If the application was previously in the background, optionally refresh the user interface.
    }

    func applicationWillTerminate(_ application: UIApplication) {
        // Called when the application is about to terminate. Save data if appropriate. See also applicationDidEnterBackground:.
    }

class ViewController: UIViewController {



    @IBOutlet weak var KronosWebsite: WKWebView!


    override func loadView() {
        KronosWebsite = WKWebView()
        self.view = KronosWebsite
    }


    override func viewDidLoad() {
        super.viewDidLoad()
        openGoogle()
    }


    func openGoogle(){
        let url2=URL(string: "http://www.google.com")
        let web = SFSafariViewController(url: url2!)
        let keyWindow = UIApplication.shared.windows.filter {$0.isKeyWindow}.first

        if var topController = keyWindow?.rootViewController {
            while let presentedViewController = topController.presentedViewController {
                topController = presentedViewController
            }
            do{
                topController.present(web, animated: true, completion: nil)

            }catch let error {
                DispatchQueue.main.async {
                    print("ERROR \(error)")
                }
            }
        }
    }
}

У меня есть эта старая функция в библиотеке 

    public func authorizeSafariEmbedded(from controller: UIViewController, at url: URL) throws -> SFSafariViewController {
        safariViewDelegate = OAuth2SFViewControllerDelegate(authorizer: self)
        let web = SFSafariViewController(url: url)
        web.title = oauth2.authConfig.ui.title
        web.delegate = safariViewDelegate as! OAuth2SFViewControllerDelegate
        if #available(iOS 10.0, *), let barTint = oauth2.authConfig.ui.barTintColor {
            web.preferredBarTintColor = barTint
        }
        if #available(iOS 10.0, *), let tint = oauth2.authConfig.ui.controlTintColor {
            web.preferredControlTintColor = tint
        }
        web.modalPresentationStyle = oauth2.authConfig.ui.modalPresentationStyle

        willPresent(viewController: web, in: nil)
        controller.present(web, animated: true, completion: nil)

        return web
    }

Я вызываю эту функцию с этими строками 

                let keyWindow = UIApplication.shared.windows.filter {$0.isKeyWindow}.first
                if var topController = keyWindow?.rootViewController {
                    while let presentedViewController = topController.presentedViewController {
                        topController = presentedViewController
                    }
                    do{
                        let web = try authorizer.authorizeSafariEmbedded(from: topController,at: url!)
                    }catch let error {
                        DispatchQueue.main.async {
                            print("ERROR \(error)")
                        }
                    }
                }

Но у меня все еще остается пустая страница, я не нашел правильной работы решение в Интернете, которое я также тестировал с помощью let url = URL (string: "http://www.google.com")

даже это не работает 

    public func authorizeSafariEmbedded(from controller: UIViewController, at url: URL) throws -> SFSafariViewController {
        let web = SFSafariViewController(url: url)
        web.title = oauth2.authConfig.ui.title
        controller.present(web, animated: true, completion: nil)

        return web
    }

Заранее спасибо

Вот что я сделал, чтобы это работало 

import UIKit
import WebKit
import SafariServices

class ViewController: UIViewController {

    var safariVC = SFSafariViewController(url: URL(string: "https://apple.com")!)

    @IBOutlet weak var KronosWebsite: WKWebView!

    override func loadView() {
        KronosWebsite = WKWebView()
        self.view = KronosWebsite
    }

    func addViewControllerAsChildViewController() {
        addChild(safariVC)
        self.view.addSubview(safariVC.view)
        safariVC.didMove(toParent: self)
        self.setUpConstraints()

    }

     override func viewDidLoad() {
          super.viewDidLoad()
          addViewControllerAsChildViewController()
      }


    func setUpConstraints() {
           self.safariVC.view.translatesAutoresizingMaskIntoConstraints = false
           self.safariVC.view.topAnchor.constraint(equalTo: self.view.safeAreaLayoutGuide.topAnchor, constant: 30).isActive = true
           self.safariVC.view.bottomAnchor.constraint(equalTo: self.view.safeAreaLayoutGuide.bottomAnchor, constant: -30).isActive = true
           self.safariVC.view.leadingAnchor.constraint(equalTo: self.view.safeAreaLayoutGuide.leadingAnchor, constant: 30).isActive = true
           self.safariVC.view.trailingAnchor.constraint(equalTo: self.view.safeAreaLayoutGuide.trailingAnchor, constant: -30).isActive = true

       }



}
