title: Is there any way to use the debugger with Siri Intents *UI* extension?
body: <p>I have written a Siri Intents extension (<em>#1</em>) with a corresponding IntentsUI extension (<em>#2</em>).  Both are working.  </p>
  
  <p>To debug the Intents extension (<em>#1</em>), I can just cmd-R for the Intents Extension scheme (with the scheme executable set to "Ask On Launch"), it runs and attaches to the debugger, as expected (<a href="https://stackoverflow.com/questions/38093871/how-do-i-debug-my-siri-intents-extension">also answered here</a>).</p>
  
  <p>After the Intents extension (<em>#1</em>) completes, the Intents <em>UI</em> extension (<em>#2</em>) runs and displays, again as expected, but it does <em>NOT</em> attach to the debugger.  </p>
  
  <p>I thought maybe I could use the same type of scheme setup for the IntentsUI extension (<em>#2</em>) as with Intents extension (<em>#1</em>), but this fails to launch at all.</p>
  
  <p>I see no way to get the IntentsUI extension (<em>#2</em>) to attach in the debugger and allow stepping through the code.</p>
