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 code should be like:
Then you can print the language out by println(result.language)
