You have to adjust the function like this in order to return a tuple.

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

    return (greeting, language)
}

let result = greeting("Tom")

println(result.language)
