iOS Swift Functions and Optionals Parameters and Tuples Tuples

I have watched the videos several times, but the question doesn't make sense to me.

i just need a little more guidance on the tuples

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

    return greeting

In many programming languages, a function can only return one single thing. However, Swift is different and allows you to return multiple items from the same function simultaneously. In this case, it wants you to return both the language and the greeting. Here was my code for step one of the challenge. Maybe it will help!

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

    return (language, greeting)

thank you!

hello there, i have been stuck on the second portion of the challenge for a while now. i can't seem to figure out how to initiate the variable result in the auction. any tips? thank you!
