title: Xcode Storyboard: Can't add View to ViewController
body: <p>I'm using Xcode 10 (with Swift 5 and for iOS 12) and my app is currently set up like this:</p>
  <ol>
  <li><code>UIViewController</code> 1 (login screen) - segue12 to -&gt;</li>
  <li><code>NavigationController</code> that automatically created</li>
  <li><code>UIViewController</code> 2 with a <code>UITableView</code> - segue23 to -&gt;</li>
  <li><code>UIViewController</code> 3 (detailed info about an item in the <code>UITableView</code> with automatically created &quot;back&quot; button)</li>
  </ol>
  <p><a href="https://i.stack.imgur.com/QzBQ1.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/QzBQ1.png" alt="enter image description here" /></a></p>
  <p>The <code>NavigationBar</code> only contains a &quot; &quot;.</p>
  <p>I now want to add another <code>UIView</code> with a button below the <code>UITableView</code> but Xcode won't let me drag it below the <code>UITableView</code>, only either into the <code>UITableView</code> or directly underneath &quot;First Responder&quot;, which puts the View outside into its own window.</p>
  <p>If I delete &quot;My Table View&quot;, it won't let me drag in a replacement either.</p>
  <p>How do I fix this, so I can add the new <code>UIView</code> + <code>UIButton</code>?</p>
