Hey Ben, You have to print it out like this:

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)

The challenge wants you to get the language element from the tuple that resuly currently holds. What you're doing is having every tuple created using greeting print out 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)
