I am really confused as to what they want us to modify in this code. Any hints?

What is the first step?

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

    return greeting
}

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

    return (greeting: greeting, language: language)
}

Change the function so it will return a tuple

Hi Mitchell,

As the Challenge is asking for both greeting and language to be returned as a tuple, you'd want to include that each is a string being returned - not just a single string, then just add the language to the return statement.

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

    return (greeting, language)
}

Hope that helps!
