title: Add another button to navigation bar
body: <p>I'm modifying an app and this app has some buttons in its navigation bar, I wanted to add another button or Bar Button item by dragging it to the hierarchy but it seems I can't add it as a child to navigation bar, I wanted to ask if you have any solutions to this, here's a snapshot of the hierarchy of the storyboard, I want to add another Bar Button Item or another Button to the Navigation item.<br/>
  Thanks<br/>
