title: Referencing a button in Swift
body: <p>So I'm pretty new but I'm trying to reference a button from another. I disable the first button when I press it, but I want to enable it when I press the other button. Check this out. It doesn't like my second sender reference.</p>
  
  <pre><code>@IBAction func IBbtnUpdateTap(sender: UIButton){
    sender.enabled = false
  }
  
  @IBAction func addSpinsButton() {
  
      sender.enabled = true
  }
  </code></pre>
  
  <p>Any ideas from you coding wizards?</p>
