I can't get the tuples challenge

I did everything I could to try to figure out how to complete it.

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

var tuple = (greeting, language)

return tuple

}

I get the error saying that I need to name the elements 'Greeting' and 'Language'.

So I did this:

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

var (greeting, language) = (greeting, language)

return ///???????

}

But now I don't know how to return it.

Can anyone help?

your first attempt was almost correct. you had 

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

    var tuple = (greeting, language)

    return tuple
}

the task states: Make sure to name each item in the tuple: greeting and language. This means the elements in the tuple in the return type need to be named. 

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

    var tuple = (greeting, language)

    return tuple
}
