  <p>My first thought was to implement this using the <a href="https://developer.apple.com/library/prerelease/ios/documentation/MultipeerConnectivity/Reference/MultipeerConnectivityFramework/index.html" rel="noreferrer">Multipeer Connectivity Framework</a>. However, it's not supported on tvOS. Is there a good way to connect an iPhone to an Apple TV without Multipeer Connectivity?</p>
  
  <p><strong>Update:</strong> It doesn't appear that I can use GameKit because GKPeerPickerController has been removed from GameKit on tvOS.</p>
