Getting all cookies from WKWebView

Question

while getting cookies from UIWebView seems straightforward by using NSHTTPCookieStorage.sharedHTTPCookieStorage(), it seems WKWebView stores the cookies somewhere else.

I did some research, and I was able to get some cookies from the grabbing it from NSHTTPURLResponse object. this, however, does not contain all the cookies used by WKWebView:

func webView(webView: WKWebView, decidePolicyForNavigationResponse navigationResponse: WKNavigationResponse, decisionHandler: (WKNavigationResponsePolicy) -> Void) {

  if let httpResponse = navigationResponse.response as? NSHTTPURLResponse {
    if let headers = httpResponse.allHeaderFields as? [String: String], url = httpResponse.URL {
      let cookies = NSHTTPCookie.cookiesWithResponseHeaderFields(headers, forURL: url)

      for cookie in cookies {
        logDebug(cookie.description)

        logDebug("found cookie " + cookie.name + " " + cookie.value)
      }
    }
  }
}

Strangely, there's also a class WKWebsiteDataStore in ios 9 that responsible for managing cookies in WKWebView, however, the class does not contain a public method to retrieve the cookies data:

let storage = WKWebsiteDataStore.defaultDataStore()

storage.fetchDataRecordsOfTypes([WKWebsiteDataTypeCookies], completionHandler: { (records) -> Void in
  for record in records {
    logDebug("cookie record is " + record.debugDescription)

    for dataType in record.dataTypes {
      logDebug("data type is " + dataType.debugDescription)

      // get cookie data??
    }
  }
})

Is there a workaround for getting the cookie data?

Finally, httpCookieStore for WKWebsiteDataStore landed in iOS 11.
