title: Xcode 8, cannot pair watch simulator
body: <p>I'm running Xcode 8 beta 5.  My app has a watch extension.  I cannot pair the iPhone simulator with the watch simulator.  I've followed the instructions for pairing (Xcode, Window, Devices) but there are no watch simulators listed there, nor are any listed when I select any of the iPhone simulators.  I've tried variations of Add Simulator, but I only get more iPhone simulators -- I never see a watch simulator or a pairing there.  The watch simulator exists -- I can launch the simulator, but it isn't paired.  I've tried deleting Xcode and re-installing.  Same issue with beta 4.</p>
  
  <p>How do I get the watch simulator to appear when I select an iPhone simulator in Device?</p>
  
  <p><strong>UPDATE:</strong> To be clear, these are Apple's instructions for "Pairing Apple Watch Simulators to iPhone Simulators" (<a href="https://developer.apple.com/library/ios/recipes/xcode_help-devices_organizer/PairingWatchestoiPhoneSimulators/PairingWatchestoiPhoneSimulators.html" rel="noreferrer">https://developer.apple.com/library/ios/recipes/xcode_help-devices_organizer/PairingWatchestoiPhoneSimulators/PairingWatchestoiPhoneSimulators.html</a>)</p>
  
  <blockquote>
    <ol>
    <li><p>In the Devices window under Simulators, select an iPhone 5 and later simulator.</p></li>
    <li><p>Under the Paired Watches table, click the Add button (+).</p></li>
    </ol>
  </blockquote>
  
  <p>I never see the "Paired Watches table" so there's no Add button.</p>
  
  <p>I do see that in Xcode 7, like this:

   <strong>UPDATE 2:</strong>
  In Xcode 8 beta 6, the Paired Watches table appears in the Devices window, but the pairing still fails with a "Simulator Not Paired" dialog. </p>
