title: Can iframes work in WKWebView with Cordova?
body: <p>According to the Apache Cordova blog, iframes may not work using WKWebView. (<a href="https://cordova.apache.org/news/2018/08/01/future-cordova-ios-webview.html" rel="noreferrer">https://cordova.apache.org/news/2018/08/01/future-cordova-ios-webview.html</a>)</p>
  
  <p>I have a Cordova application that is in the App Store that relies quite heavily on iframes. Since UIWebView is likely to be removed in iOS 13, is there a way to get iframes working using WKWebView?</p>
  
  <p>Here's what I've done so far:</p>
  
  <p>I tried using the Ionic WebView plugin (<a href="https://github.com/ionic-team/cordova-plugin-ionic-webview" rel="noreferrer">https://github.com/ionic-team/cordova-plugin-ionic-webview</a>), and although it works for parts of my app it does not work on the iframe pages. Specifically, I'm getting Access-Control-Allow-Origin header contains the invalid value 'null'. I don't get this error using UIWebView. </p>
