title: How to Create Two WkWebView
body: <p>I am trying to create an iPhone app with two WKWebView, 
  one for a header and one for a container. How can I create them?</p>
  
  <p>I can't find any utility in Xcode/Interface Builder to create WKWebview instances. I can create a WebView which is of type UIWebView, but I can't call WkWebView methods on it and I can't conversion it to a WKWebview.</p>
