Which task are you stuck on?

In the first task you must make 2 modifications.

First step is to specify that you're returning a tuple with 2 strings, greeting and language, instead of just a single string.

// Before
func greeting(person: String) -> String {

// After
func greeting(person: String) -> (greeting: String, language: String) {

Second step is to change the actual return value so that you're returning a tuple instead of just a string

// Before
return greeting

// After
return (greeting, language)

Found it.

Question One

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

        return (greeting, language)
    }

Question Two

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

    return (greeting, language)
}

var result = greeting("Tom")

Question Three

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

println(result.language)
