title: View shows up in Debug View Hierarchy, but NOT on device/sim
body: <p>This issue is seriously perplexing me. I have a small UIView I'm using to show which button is selected. However, it's not showing up in my app — it should be under "Local Activities," but doesn't show up:</p>

  <p>That's fine, I thought, I'll just debug the view hierarchy and see where it is! And it looks like it's exactly where it should be:</p>

  <p>Does anyone know what might be going on here? Thanks for the help!</p>
