title: Enable Camera and Mic access in wkwebview
body: <p>I have a mobile-optimized web app that makes use of <code>getUserMedia</code> to access webcam and mic resources.</p>
  
  <p>I'm wrapping this app in a <code>WKWebView</code> as I want to offer a native app experience.  I'm aware that iOS doesn't allow camera access via browsers - however is there any way to gain permissions to the webcam/mic with native code (alongside the wrapper) and feed this to the web app - perhaps by somehow pointing <code>getUserMedia</code> to a local stream source?</p>
