title: Multiple Simultaneous Animations on Single UIView using Swift
body: <p>I've created an animation block using UIView animations - but the animation is triggered on the UITextView for every letter the player types (it's a typing game). The moment a new letter is typed, it instantly completes the previous character's animation - no overlap is possible. How would I allow for multiple animations to start and finish without interrupting each one?</p>
  
  <p>Current animation block:</p>
  
  <pre><code>UIView.transitionWithView(textViewForPlayer, duration: 0.1, options: .BeginFromCurrentState | .TransitionCrossDissolve | .AllowAnimatedContent, animations: {
      self.textForPlayer.addAttribute(
          NSForegroundColorAttributeName,
          value: UIColor.clearColor(),
          range: nsRangeOfTextShown)
      self.textViewForPlayer.attributedText = self.textForPlayer
      }, completion: { finished in
          UIView.transitionWithView(self.textViewForPlayer, duration: 2.1, options: .BeginFromCurrentState | .TransitionCrossDissolve | .AllowAnimatedContent, animations: {
              self.textForPlayer.addAttribute(
                  NSForegroundColorAttributeName,
                  value: UIColor.greenColor(),
                  range: nsRangeOfTextShown)
              self.textViewForPlayer.attributedText = self.textForPlayer
              }, completion: { finished in
          })
          println("FINISHED2")
      }
  )
  </code></pre>
