title: 'Set<NSObject>' does not have a member named 'anyObject." - Xcode 6.3
body: <p>I'm checking to see if an element has been selected. </p>
  
  <pre><code>func touchesBegan(touches: Set&lt;NSObject&gt;, withEvent event: UIEvent)
  {
      // First, see if the game is in a paused state
      if !gamePaused
      {
          // Declare the touched symbol and its location on the screen
          let touch = touches.anyObject! as? UITouch
          let location = touch.locationInNode(symbolsLayer)
  </code></pre>
  
  <p>And this had previously compiled fine in Xcode 6.2 but with a 6.3 update, the line "let touch = touches.anyObject! as? UITouch" is throwing the error:</p>
  
  <p>'Set' does not have a member named 'anyObject'</p>
  
  <p>I've read through many similar question, but I can't seem to wrap my head around "To use the value, you need to “unwrap” it first." Especially because the answers seem to focus on notifications.</p>
  
  <p>Thank you so much.
