How does my function needs to return a tuple with elements named 'greeting' and 'language'?

I'm on Challenge Task 1 of Tuples and I put in my code below but I got the error...

Your function needs to return a tuple with elements named 'greeting' and 'language'.

What did I need to change in my code in order to accmpolish this?

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

    return greeting
    return language
}

Hi Zachary,

1) In the function header, we'll type a return arrow and then specify the data types of the two return values (that's where the idea of tuples is coming into play... we're dealing with multiple elements)... String, and another String. The challenge asks us to include the names of the elements ('language' and 'greeting') of our tuple, so we'll be sure to do that. 2) We should keep the function's return statement to one line in which both values that we want to return are included. Keeping the return statement to one line is syntactically essential: once a return statement is computed, the role of the function is supposed to be done.

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

    return (greeting, language)
}

Hope this helps!
