iOS - not able to add http header of URLRequest

I am trying to add http header to URLRequest, which I am loading in WKWebView.

I tried this code:

    var urlRequest = URLRequest(url: URL(string: "url")!)
    urlRequest.addValue("value", forHTTPHeaderField: "key")
    self.viewerWebKit.load(urlRequest)

and also this:

    var urlRequest = URLRequest(url: URL(string: "url")!)
    urlRequest.setValue("value", forHTTPHeaderField: "key")
    self.viewerWebKit.load(urlRequest)

But when I am printing http headers with this code:

func webView(_ webView: WKWebView, decidePolicyFor navigationResponse: WKNavigationResponse, decisionHandler: @escaping (WKNavigationResponsePolicy) -> Void) {
    let headers = (navigationResponse.response as! HTTPURLResponse).allHeaderFields
    for (key,value) in headers {
        print("key \(key) value \(value)")
    }
    decisionHandler(.allow)
}

nothing is added or set. What am I doing wrong?

URLRequest immutable so if you want to add header in that request you need to make it mutable.use this extension to add header.

extension URLRequest {

internal mutating func addHeaders() {

        let mutableRequest = ((self as NSURLRequest).mutableCopy() as? NSMutableURLRequest)!


            mutableRequest.setValue("your header", forHTTPHeaderField: "key")
            self = mutableRequest as URLRequest

        }
    }

}

Use where you want to set Header:

request.addHeaders()

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

Use this delegate function. You can find headers of request in navigationAction.request.
