title: ViewWillAppear not executing code
body: <p>I've got this block of code in my ViewWillAppear method which simply moves a set of labels down off the screen:</p>
  
  <pre><code>override func viewWillAppear(animated: Bool) {
      super.viewWillAppear(animated)
  
      //Hide 1,3,5 RM labels
      oneRepMax.center.y += view.bounds.height
      threeRepMax.center.y += view.bounds.height
      fiveRepMax.center.y += view.bounds.height
  
  }
  </code></pre>
  
  <p>All 3 labels have been properly linked to my storyboard file. When I run the project, nothing happens.</p>
  
  <p>If I copy the exact same code into a method linked to a button, it works as expected.</p>
  
  <p>There isn't anything else in the project so i'm puzzled as to why this doesn't work.</p>
  
  <p>I'm using Xcode 7 and following a tutorial where this is working in the ViewWillAppearMethod.
   as follows:</p>
  
  <pre><code>override func viewWillAppear(animated: Bool) {
      super.viewWillAppear(animated)
  
      heading.center.x -= view.bounds.width
      username.center.x -= view.bounds.width
      password.center.x -= view.bounds.width
      loginButton.center.y += 30
      loginButton.alpha = 0
  
  
  
  }
  </code></pre>
