Why aren't I receiving the correct output or return?

For some reason I keep getting an error on this code. I'm not sure what I'm not doing here.

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

    return (language, greeting)
}

var result = greeting("Tom")

One small issue: you have greeting and language reversed: return (language, greeting). It should be the other way round. Otherwise, right on!

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)
