title: How can you see the XCUIElement tree?
body: <p><strong>Background:</strong> </p>
  
  <p>I'm experimenting with ui level testing in iOS 9.0 with XCode GM. </p>
  
  <p><strong>Question:</strong></p>
  
  <p>Is there a command in XCode GM that will allow you to see a 'tree' of accessible elements and their relationships? Something similar to the 'page' command in Appium? </p>
  
  <p>Ideally I would be able to run a command in the debugger that would give me a list of elements available for selection/manipulation. Currently you can use debugDescription on a single XCUIElement but that only gives you info for that element. </p>
