Have no idea how to print out the value of the language element from the result

Have tried a coupe of variations on my code and cannot get it to work. By best effort is below.

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

    return (greeting,language)
}

var result = greeting("Tom")

println(\(_,language))

you use dot syntax:

tupleName.elementName

so to access the language element you would use

println(result.language)

however in your return type you have the tuple listed as (language: String, greeting: String) but it should be (greeting: String, language: String). you need to fix that:

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)
