how to get cookie from urlrequest in iOS wkwebview

func webView(_ webView: WKWebView, decidePolicyFor navigationAction: WKNavigationAction, decisionHandler: @escaping (WKNavigationActionPolicy) -> Void) {
    var req = navigationAction.request;
    let cookie = req.value(forHTTPHeaderField: "Cookie");
    print(cookie) // always nil

    decisionHandler(.allow);
}

I want to get the session after user login, but the cookie is always nil;how can I get it ?

Why don't use WKWebView's API that appeared since iOS 11

webView.configuration.websiteDataStore.httpCookieStore.getAllCookies() { cookies in
    // do what you need with cookies
}

One advantage is that this method tracks HttpOnly cookies as well.

Cookie is generally stored in variable document.cookie in browser. You can access it by executing Javascript code. In this case simply "document.cookie" would return the cookies.

   let cookieScript = "document.cookie;"
   webView.evaluateJavaScript(cookieScript) { (response, error) in
            if let response = response {
                    print(response as! String)
                }
   }
