Hi kask,

  • Per the instructions, each member should have a String value for its associated value. In your code sample, you have the iPhone member set up to expect an Int: try String instead, and do that for each of the members.

  • You will want to assign "6S" to an instance of MobilePhone, and specifically to the iPhone member of that instance. For the syntax for how to do that:

enum MobilePhone {
  case iPhone(String)
  case Android(String)
  case Blackberry(String)
  case WindowsPhone(String)
}

let iPhone = MobilePhone.iPhone("6S")

Hope this helps!
