title: View in ContainerView in swift 4
body: <p>I have a project like this:
  <a href="https://i.stack.imgur.com/7Psun.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/7Psun.jpg" alt="http://serwer1356363.home.pl/pub/IMG_3307.JPG"></a></p>
  
  <p>I shared the main screen on the 2nd view:</p>
  
  <p>view from the menu (left)
  view with containerview (right).
  I would like to display further views in the right containerview (like on the screenshot).</p>
  
  <p>Is this option with containerview possible?
  How to do it? Does anyone have any examples?</p>
