title: Calendar Changed in Swift 3?
body: <p>Hey so I'm working on this little app and I<a href="https://i.stack.imgur.com/NKqou.png" rel="nofollow"><img src="https://i.stack.imgur.com/NKqou.png" alt="enter image description here"></a></p>
  
  <pre><code>let durationDateComponents = Calendar(identifier: Calendar.Identifier.gregorian).dateComponents([.year, .month, .day, .hour, .minute, .second], from: Date(), to: christmasDay, options: [])
  </code></pre>
  
  <p>What do I do here? I get that the error is pointing me to change something with the array, but what?</p>
  
  <p>Thanks!</p>
