title: NavigationBarButton Not Showing
body: <p>Is it common issue when connecting tabBarController using <code>storyboard?.instantiateViewController(withIdentifier:)</code>, the navigationBarButtons don't show ? And is there a proper way to fix this particular issue ? Because when I connect the views using segue, the buttons show just fine on navigationBar .. </p>
  
  <p>Please help.</p>
  
  <p>It's a big project, I couldn't take a picture of the whole project but this is a small part of it.</p>
