title: How to Assert an Obscured XCUIElement is Not Hittable on Screen with Xcode UI Testing
body: <p>I hope I can clearly explain what I'm about to ask -- please be patient with me if the clarity isn't there yet.</p>
  
  <p>I'm encountering a snag with UI Testing when it comes to views in the view hierarchy that are "hidden" behind other top-facing views. I know <code>XCUIElement</code> objects have the <code>exists</code> and <code>isHittable</code> interfaces that we can leverage, but these interfaces are not helping me in my trying to assert that an element is not hittable when it's obscured behind a view that's blocking it from sight.</p>
  
  <p>Anybody have insight in how to properly assert this?</p>
