WKWebView 不会加载（NSViewController，OS X）

Question

I am trying to build a simple WKWebView application that will display Google in the WebView.我正在尝试构建一个简单的 WKWebView 应用程序，它将在 WebView 中显示 Google。 The app works perfectly fine;该应用程序运行良好； however, upon implementing the WKWebView, the app no longer shows a window.然而，在实施 WKWebView 后，应用程序不再显示窗口。 It just simply launches the app (in the dock) with no NSView in sight.它只是简单地启动应用程序（在 dock 中），看不到 NSView。

ViewController.swift视图控制器.swift

import Cocoa
import WebKit

class ViewController: NSViewController {

    var webView: WKWebView?

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

        let url = NSURL(string:"http://www.google.com/")
        let req = NSURLRequest(URL: url!)
        self.webView!.loadRequest(req)
    }

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

    override var representedObject: AnyObject? {
        didSet {
        // Update the view, if already loaded.
        }
    }


}

There doesn't seem to be any further examples online, nor does there seem to be any projects on GitHub.网上好像没有更多的例子，GitHub 上好像也没有什么项目。

Thanks.谢谢。 I haven't come across this before.我以前没有遇到过这个。

I guess there're some limitations behind Xcode Settings those hidden settings make your WKWebView NOT WORK!!! 我想Xcode设置背后有一些限制，那些隐藏的设置会使您的WKWebView无法正常运行！！！

You could try these ways, Maybe you will find the solution: 您可以尝试以下方式，也许您会找到解决方案：

1) Search these key words by Google, You'll find some tutorials: 1）通过Google搜索这些关键词，您将找到一些教程：

<key>NSAppTransportSecurity</key>
<dict>
    <key>NSAllowsArbitraryLoads</key>
    <true/>
</dict>

2) Check your Project Setting panel. 2）检查项目设置面板。 Make sure you've CHECKED the NetWork [Incoming] & [OutComing] item: 确保已检查NetWork [Incoming]和[OutComing]项目：

With Xcode 14 I needed the 'outgoing connection' and additionally the frame:对于 Xcode 14，我需要“传出连接”以及框架：

var webView: WKWebView!

override func loadView() {
    // these two lines are important:
    super.loadView()
    webView = WKWebView(frame:self.view.frame)

    view = webView
    
    let url = URL(string:"https://www.example.com/")!
    let req = URLRequest(url: url)
    webView.load(req)
    
    // webView.loadHTMLString("<html><body bgcolor=red><p>Hello, World!</p></body></html>", baseURL: nil)
}
