title: @IBInspectable with enum?
body: <p>I'd like to create <code>@IBInspectable</code> element as you see at the picture below : </p>
  
  <p><img src="https://i.stack.imgur.com/EpFXL.png" alt="enter image description here"></p>
  
  <p>my idea is to use something like enum as type for <code>@IBInspectable</code>, but it looks like it's not the case, any ideas how to implement element like this ?</p>
  
  <p>EDIT:</p>
  
  <p>It looks like <code>@IBInspectable</code> supports only these types :</p>
  
  <ul>
  <li><code>Int</code></li>
  <li><code>CGFloat</code></li>
  <li><code>Double</code></li>
  <li><code>String</code></li>
  <li><code>Bool</code></li>
  <li><code>CGPoint</code></li>
  <li><code>CGSize</code></li>
  <li><code>CGRect</code></li>
  <li><code>UIColor</code></li>
  <li><code>UIImage</code></li>
  </ul>
