Error: "result variable has wrong value in it", even though it right

heres my code:

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

    return greeting
}

let result = greeting("Tom")

i get a stupid error that says that the result variable has the wrong value in it even thought i am returning language and Tom.

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

    return greeting
}

let result = greeting("Tom")

task 1 states: Make sure to name each item in the tuple: greeting and language

Its not entirely clear but greeting needs to be the first element in the tuple and language second. change your return type and the return tuple around 

// change the return type so that greeting is first, and language second
func greeting(person: String) -> (greeting: String, language: String) {
    let language = "English"
    // make the greeting the first element, and language second
    var greeting = ("Hello \(person)", language )

    return greeting
}

let result = greeting("Tom")

I just passed task 1 and 2 using the code above. Make sure you have everything typed/spelled correctly
