Task 3 of 3, had troubles with every single challenge of the tuples. Can you guys help me with this too?

Using the println I should assign the value og language to the variable return

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

    return (greeting, language)
}

var result = greeting("Tom") {
println("language")
}

Challenge Task 3 of 3 "Using the println statement, print out the value of the language element from the result tuple."

asks you to print out the "language" element from the result tuple "result" like this: println(result.language)

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)
