title: How to Migrate to WKWebView?
body: <p>I'm trying to understand how to make use of the new WKWebView in iOS8, can't find much information. I've read:</p>
  
  <p><a href="http://developer.telerik.com/featured/why-ios-8s-wkwebview-is-a-big-deal-for-hybrid-development/">http://developer.telerik.com/featured/why-ios-8s-wkwebview-is-a-big-deal-for-hybrid-development/</a>
  <a href="http://nshipster.com/wkwebkit/">http://nshipster.com/wkwebkit/</a></p>
  
  <p>But how does this affect existing apps? Will an ordinary UiWebView get the speedup from the nitro java script engine or do we need to make changes? How do we deal with backwards compatibility?</p>
  
  <p>All the code and examples I can find are using swift, will this be mandatory?</p>
  
  <p>Thankful for any help on this matter!</p>
