title: Adding view controller in scrollview
body: <p>I am currently working on an app that has been developed using storyboards. </p>
  
  <p>I am trying to add a view controller programmatically into a paging scroll view at the beginning before 2 other views that are already added within the storyboard. </p>
  
  <p>The view controller gets added but the width is slightly larger and goes across into the middle view.</p>
  
  <pre><code>let vc = Vc()
  scrollView.addSubview(vc.view)
  </code></pre>
