title: Swift: Scroll view with image view isn't enabled?
body: <p>So I created a scroll view and put an image view in it. I initialized the scroll view as a variable and wrote the following code in my ViewController and yet, the image won't scroll. 
  What's wrong?</p>
  
  <p>Later on I'm also going to need to put several buttons into this scroll view so if I'm missing something here, it'd be great if you could address it for buttons as well.</p>
  
  <p>My code:</p>
  
  <pre><code>import UIKit
  
  class ViewController: UIViewController {
  
      override func viewDidLoad() {
          super.viewDidLoad()
          // Do any additional setup after loading the view, typically from a nib.
          ScrollView.scrollEnabled = true
  
      }
      @IBOutlet weak var ScrollView: UIScrollView!
  
      override func didReceiveMemoryWarning() {
          super.didReceiveMemoryWarning()
          // Dispose of any resources that can be recreated.
      }
  
  
  }
  </code></pre>
