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

return both

}

var result = greeting(person: "Tom")

println(result) println(result.greeting) println(result.language)

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

You have to reverse your parameters greeting and language:

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

    return both
}

var result = greeting(person: "Tom")
