I don't think I'm missing anything in the code, and it is still marking it wrong.

I copy pasted the code into Xcode and called the function with a person's name and it keeps telling me that the name is an unresolved identifier.

tuples.swift 
func greeting(person: String) -> (String, String) {
    let language = "English"
    let greeting = "Hello \(person)"

    return (greeting, language)
}

Looks like you're missing the last bit about naming the items in the tuple.

Thank you, but what do you mean by that?

A named tuple is in the form

  (name: value)

To use them as a return value you'll also need to modify your function definition to reference the names. For more information check out our blog post about tuples in swift.
