How to get headers from WKWbView finish loads

I am using WKWebView in app & i am looking for getting all headers from wkwebview in finish loads method webView(_ webView: WKWebView, didFinish navigation: WKNavigation!) { Just like in UIWebView

func webViewDidFinishLoad(_ webView: UIWebView) {
        print("Finished loads---", webView.request?.allHTTPHeaderFields)
    }

How can we achieve that in WKWebView ?

You need to set your view controller as the WKWebView Navigation Delegate WKNavigationDelegate and implement its decidePolicyFor method:

optional func webView(_ webView: WKWebView, decidePolicyFor navigationAction: WKNavigationAction, decisionHandler: @escaping (WKNavigationActionPolicy) -> Void)

Try like this:

func webView(_ webView: WKWebView, decidePolicyFor navigationAction: WKNavigationAction, decisionHandler: @escaping (WKNavigationActionPolicy) -> Void) {
    let allHTTPHeaderFields = navigationAction.request.allHTTPHeaderFields ?? [:]
    for (key, value) in allHTTPHeaderFields {
        print("key:", key, "value:", value)
    }
    
    if navigationAction.navigationType == .linkActivated  {
        if let url = navigationAction.request.url,
            let host = url.host, !host.hasPrefix("www.google.com"),
            UIApplication.shared.canOpenURL(url) {
            UIApplication.shared.open(url)
            print(url)
            print("Redirected to browser. No need to open it locally")
            decisionHandler(.cancel)
        } else {
            print("Open it locally")
            decisionHandler(.allow)
        }
    } else {
        print("not a user click")
        decisionHandler(.allow)
    }
}
