Hi there!

When I go to another web page, the swift's navigation bar is superimposed on the site's navigation bar (simulator). For two days I can't find what could be the reason. Launched the lecturer's project (4 project 100 days of swift) and exactly the same problem. Could this issue be related to upgrading to the latest version of Xcode?

import UIKit
import WebKit

class ViewController: UIViewController, WKNavigationDelegate {
    var webView: WKWebView!

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

    override func viewDidLoad() {
        super.viewDidLoad()
        navigationItem.rightBarButtonItem = UIBarButtonItem(title: "Open", style: .plain, target: self, action: #selector(openTapped))

        let url = URL(string: "https://www.hackingwithswift.com")!
        webView.load(URLRequest(url: url))
        webView.allowsBackForwardNavigationGestures = true

    }

    @objc func openTapped() {
        let ac = UIAlertController(title: "Open page…", message: nil, preferredStyle: .actionSheet)
        ac.addAction(UIAlertAction(title: "apple.com", style: .default, handler: openPage))
        ac.addAction(UIAlertAction(title: "hackingwithswift.com", style: .default, handler: openPage))
        ac.addAction(UIAlertAction(title: "Cancel", style: .cancel))
        ac.popoverPresentationController?.barButtonItem = navigationItem.rightBarButtonItem
        present(ac, animated: true)
    }

    func openPage(action: UIAlertAction) {
        guard let actionTitle = action.title else { return }
        guard let url = URL(string: "https://" + actionTitle) else { return }
        webView.load(URLRequest(url: url))
    }

    func webView(_ webView: WKWebView, didFinish navigation: WKNavigation!) {
        title = webView.title
    }

}
