title: RTCMTLVideoView not supported in iPhone 11 series
body: <p>I'm working on Video calls using WebRTC. I've used RTCMTLVideoView to render the remote's video in the app. Except iPhone 11 series devices, all other devices were working fine.</p>
  <pre><code>  #if arch(arm64) // Using metal (arm64 only)
      remoteRenderer = RTCMTLVideoView(frame: showInView.bounds)
    #endif
  </code></pre>
  <p>I'm checking the issue in iPhone 11 Pro 13.3.1 &amp; iPhone XS 13.2.3 and iPhone 6 12.3. But iPhone 11 alone getting this issue. Do we have any solutions for this Remote Video rendering issue?</p>
