WKWebView 不会显示我需要它的网页

Question

鉴于下面的代码。我无法显示“https://baycare.clearstep.health/covid19”网页。它在 Safari 中显示正常，我可以让其他页面显示在 WKWebView 中。我已经尝试实现所有的导航和 ui 委托方法来尝试追踪问题，但没有找到任何东西。

该 URL 过去可以使用，但该公司已经更改了某些内容，而现在却没有。任何帮助表示赞赏。

下面是一个完整的程序：

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

    var window: UIWindow?

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {

        let controller = UIViewController()
            .setup { viewController in
                WKWebView(frame: viewController.view.bounds)
                    .setup {
                        viewController.view.addSubview($0)
                        $0.uiDelegate = WebViewUIDelegate.instance
                        $0.navigationDelegate = WebViewDelegate.instance
                        $0.autoresizingMask = [.flexibleWidth, .flexibleHeight]
                        $0.load(URLRequest(url: URL(string: "https://baycare.clearstep.health/covid19")!))
                    }
            }
  
        window = UIWindow(frame: UIScreen.main.bounds)
        window?.rootViewController = controller
        window?.makeKeyAndVisible()

        return true
    }
}

extension NSObjectProtocol {
    @discardableResult
    func setup(_ fn: (Self) -> Void) -> Self {
        fn(self)
        return self
    }
}

final class WebViewUIDelegate: NSObject, WKUIDelegate {
    static let instance = WebViewUIDelegate()
}


final class WebViewDelegate: NSObject, WKNavigationDelegate {

    static let instance = WebViewDelegate()

    func webView(_ webView: WKWebView, didFail navigation: WKNavigation!, withError error: Error) {
        print("This doesn't fire so no error?", error)
    }
}

WKWebView 是贬低版本，但 webview 仍然可以正常工作，我遇到了同样的问题，我也在做同样的事情，但后来我使用了 web view 而不是 WKWenView

导入 UIKit 导入 WebKit

class PolicyVC: UIViewController {

    @IBOutlet weak var webView: UIWebView!
    
    var isPolicyView = false
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        let button = UIButton(type: UIButton.ButtonType.custom)
        button.setImage(UIImage(named: "ic_arrow_left"), for: .normal)
        button.addTarget(self, action:#selector(popView), for: .touchUpInside)
        button.frame=CGRect(x: 0, y: 0, width: 20, height: 20)
        let barButton = UIBarButtonItem(customView: button)
        self.navigationItem.leftBarButtonItems = [barButton]
        setUpUI()
        
       }

    @objc func popView(){
        self.navigationController?.popViewController(animated: true)
    }
    
    override func viewWillAppear(_ animated: Bool) {
       super.viewWillAppear(animated)
    
         self.navigationController?.navigationBar.isTranslucent = true
         self.navigationController?.navigationBar.isHidden = false
         self.navigationController?.navigationBar.backgroundColor = .black
    }
    
    func setUpUI(){
        
        if isPolicyView{
            let url = URL(string: "https://www.termsfeed.com/privacy-policy/68c4cdaeba7e146a7d72bf57654520e7")
            let urlRequest = URLRequest(url: url!)
            webView.loadRequest(urlRequest)
        }else{
            let url = URL(string: "https://www.termsfeed.com/terms-conditions/0001db2c7a1061a55e2f933bb94102de")
            let urlRequest = URLRequest(url: url!)
            webView.loadRequest(urlRequest)
        }
        
    }

}
