title: Add a ScrollView to existing View
body: <p>I'm developing a little app in Swift 2.0. I have a View with the following hierarchy:</p>
  
  <p><a href="https://i.stack.imgur.com/aS9aY.png" rel="noreferrer"><img src="https://i.stack.imgur.com/aS9aY.png" alt="enter image description here"></a></p>
  
  <p>Now, the elements placed in this view can't be displayed entirely in it, so I would like to use a <code>ScrollView</code> in order to be able to scroll all the content. </p>
  
  <p>How I can embed all the content of my <code>View</code>to a new <code>ScrollView</code>? Can I do this programmatically by code?</p>
