About Challenge Take 2 of 3 in Parameters and Tuples Step

What is wrong code about this? I don't know how to fix.

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

    return greeting
}

let result = greeting(person: "Tom")

Try this - should work. 

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

    return (greeting, language)
}

var result = greeting("Tom")

Try it this way:

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

    return (greeting, language)
}

let languageGreeting: (greeting:String, language:String) = greeting(person: "Tom")

You simpley forgot to give the language as well.

so in your example you used

return greeting

nothing about the language. as it is a tuple, you use something like

return (greeting, language)

Your constant will then be something like:

let languageGreeting: (greeting:String, language:String)

I hope this helps

I believe the task asks you to create a variable instead of a constant, so you should be using var result, instead of let result
