title: How do you present a view controller in a SKScene?
body: <p>I am trying to figure out how to use a share sheet for my SpriteKit game and when I try to present the view controller from my scene, it gives me an error.</p>
  
  <pre><code>if self.nodeAtPoint(location) == self.shareButton {
          var tempMessage = "I just got \(score) on [insert app]"
  
          let activityVC:UIActivityViewController = UIActivityViewController(activityItems: [tempMessage], applicationActivities: nil)
  
          self.presentViewController(activityVC, animated: true, completion: nil)
  }
  </code></pre>
  
  <p>This is in my GameOverScene. How exactly do you go about managing viewcontrollers in Swift because the answers I have seen were in OBJ-C.</p>
  
  <p>Thanks!</p>
