The task wants you to name the elements of the tuple you return. As your code is right now, the tuple you return would just have index-based element names, like .1 and .2.

You correctly adjusted the return type to (String, String), but you can give each of those tuple elements names. For example:

func wholeNameToLastName(name:String) -> (firstName:String, lastName:String) {
    // break name into parts here
    return (firstName, lastName)
}

So you just need to do something similar for your specific task.
