What am I doing wrong with Swift Functions and Optionals Challenge Task 2 of 2

import UIKit

func greeting(#person: String){ greeting(person: "Jerry") } Doesn't the above code call that function? I keep failing this one and getting the "bummer" notice, but cannot seem to get past this.

You are calling the function inside the function. 

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

    return (language, greeting)
}

let result = greeting("Tom")

println(result.language)

Try this:

let result = greeting("Tom") // Change this to var

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

var result = greeting("Tom")

println(result.language)
