I laid out the UI,  made it a component,  then added a stack view with it set to the initial item set to that component.  The UI appeared for a second then disappeared.  The app was still running.  I fiddled with it a bit,  if I fixed the disappearing problem,  then it didn't layout the  UI correctly.
