Talking to the Live View updated for iOS 10.0.1

I updated the WWDC Talking to the Live View sample app for iOS 10.0.1. As usual, the updates are to get it on Swift 3 as it is implemented.

  1. Use @escaping for function arguments that you assign to member variables
  2. Extensions cannot access private functions in the class they are extending
  3. Arguments in function variable types should not have names (use _ instead)
