Try only below

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

    return (greeting, language)
}

When you click on tuples.swift it takes you directly to the code challenge.

Hello, greeting function is returning a tuple. Since it is not named tuple you can do this:

let (greeting, language) = greeting("Tom")

then you can do 

println("\(language)")

or 

println("\(greeting)")

Try below: You will need to set named tuple as return value then you can use it as result.language

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

    return (greeting, language)
}

var result = greeting("Tom")

For setp2 you should not create var result = greeting("Tom") part i guess. Just remove that line
