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

    //return the tuple
    return (greeting, language)
}

var result = greeting("Tom")
println(result.language) // return language value not both

// You had
// println(result.language.greeting)

You just need to return the language value in the tuple, not both.
