CodePudding user response：

The UIView.load() method you are calling doesn't take any arguments, so XCode is correct in their assessment. You can control-click on the .load method and go to the documentation to verify this.

What you probably wanted to do is pass the URLRequest to the WKWebView that you're creating. By making the return value of makeUIView specific (so not using some to make it opaque), the updateUIView method will also recognize it as the incoming uiView. You can then call the correct WKWebView.load(_:) on it:

struct WebView: UIViewRepresentable {
    var url: URL
    
    func makeUIView(context: Context) -> WKWebView {
        WKWebView()
    }
    
    func updateUIView(_ uiView: WKWebView, context: Context) {
        let request = URLRequest(url: url)
        uiView.load(URLRequest(url: url))
    }
}

CodePudding user response：

Change your updateUIView to so that you call load on your web view instance instead

func updateUIView(_ webView: WKWebView, context: Context) {
    let request = URLRequest(url: url)
    webView.load(request)
}
