title: How to use Hero framework?
body: <p>I'm learning to use this popular animation framework on Github: <a href="https://github.com/lkzhao/Hero" rel="noreferrer">https://github.com/lkzhao/Hero</a></p>
  
  <p>I built a test project, like this: </p>
  
  <p><a href="https://i.stack.imgur.com/veefV.png" rel="noreferrer"><img src="https://i.stack.imgur.com/veefV.png" alt="enter image description here"></a></p>
  
  <p>This is my <code>ViewController</code>: </p>
  
  <pre><code>class ViewController: UIViewController {
  
      @IBOutlet weak var animationObject: UIImageView!
  
      override func viewDidLoad() {
          super.viewDidLoad()
  
          isHeroEnabled = true
          animationObject.heroModifiers = [.fade, .translate(x:0, y:-250), .rotate(x:-1.6), .scale(1.5)]
      }
  }
  </code></pre>
  
  <p>When I ran the project, the view doesn't move. I have no idea how to make it work from the wiki page of <code>Hero</code>, so is there somebody who can give me a hint? </p>
