How to make this Tuple work?

Tried let result = greeting(person: "Tom") as well.

Does it have something to do with the function and the variable being required to have the same name?

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

    return (language, greeting)
}

let (language, hello) = greeting("Tom")
let result = greeting("Tom")

Hi Jack, I used a Tuple before... best way is to show you my example...

let colors = getColors(dataModel.nonLocalisedName)
dataModel.lightColor = colors.light
dataModel.darkColor = colors.dark
dataModel.fadedColor = colors.faded

So for your example above try the below (I've set a let for each but you can call it directly if needed).

let theGreeting = greeting("Tom")
let language = theGreeting.language
let theActualGreeting = theGreeting.greeting

// or you can call it directly
print("Language is \(theGreeting.language)")

Hope it works for you.
