I can't get to the next step while I do it exactly as said. It seems to not compile it right.

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

    var g = (greeting: greeting, language: language)

    return g
}

var (greeting, language) = greeting("Jaap")

println(greeting)

For one, the functions return type statement needs to be a tuple including language and greeting. As so...

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

    return (greeting, language)
}
