未加载Xcode Webview项目

Question

我有一个带有Webview和TabBar的Xcode项目，使用TabBar可以在WebView之间切换。我的问题是，当我在Lieferworld.de 下的ShoppingCard中放入一些东西，并使用TabBar切换到我的购物卡url时，其中的项目不可见。我该如何解决？ ShoppingCard URL以.php结尾。下面是实现的代码

Viewhome：

@IBOutlet var webViewHome: WKWebView!


 override func loadView() {
       let webConfiguration = WKWebViewConfiguration()
       webViewHome = WKWebView(frame: .zero, configuration: webConfiguration)
       webViewHome.uiDelegate = self
       webViewHome.configuration.preferences.javaScriptEnabled = true
       //webViewHome.configuration.preferences.javaEnabled = true

       view = webViewHome

}

override func viewDidLoad() {
    super.viewDidLoad()

    let url = URL(string: "https://lieferworld.de")
    let request = URLRequest(url: url!)
    webViewHome.configuration.preferences.javaScriptEnabled = true
    //webViewHome.configuration.preferences.javaEnabled = true
    webViewHome.load(request)

@IBAction func GoBackHome(_ sender: Any) {


    if webViewHome.canGoBack {

        webViewHome.goBack()

    }

}

我实现了WKNavigationDelegate，但是对于实现Delegates，您能给我看一个示例代码吗？

顺便说一句，非常感谢您的回答
