import SwiftUI
import WebKit

typealias WebCallBack = ((String?) -> Void)?

class MyWKDelegate: NSObject, WKNavigationDelegate {
    private var webCallBack: WebCallBack = nil

    init(webCallBack: WebCallBack) {
        self.webCallBack = webCallBack
    }

    func webView(_: WKWebView, decidePolicyFor navigationAction: WKNavigationAction, decisionHandler: @escaping (WKNavigationActionPolicy) -> Void) {
        webCallBack?(navigationAction.request.url?.absoluteString)
        decisionHandler(.allow)
    }

    func webView(_: WKWebView, didFinish _: WKNavigation!) {
        print("End loading")
    }
}

class MyScriptDelegate: NSObject, WKScriptMessageHandler {
    func userContentController(_: WKUserContentController, didReceive message: WKScriptMessage) {
        print("WKScriptMessageHandler", message.body)
    }
}

struct WebView: UIViewRepresentable {
    let webView: WKWebView
    let delegate: MyWKDelegate

    internal init(urlStr: String, webCallBack: WebCallBack) {
        let config = WKWebViewConfiguration()

        webView = WKWebView(frame: .zero, configuration: config)
        delegate = MyWKDelegate(webCallBack: webCallBack)

        webView.navigationDelegate = delegate

        if let url = URL(string: urlStr) {
            webView.load(URLRequest(url: url))
        }
    }

    private func getConfiguredWebview() -> WKWebView {
        return webView
    }

    func makeUIView(context _: Context) -> WKWebView {
        return webView
    }

    func updateUIView(_: WKWebView, context _: Context) {}
}

//Usage

WebView(urlStr: "some url", webCallBack: { (d: String?) in
    print(d)
})
