Swift Tuples challenge task 2 looks good in playground, but Bummer

I'm using Safari browser. If I copy my code into an Xcode playground the variable result is the tuple returned from greeting so I don't understand why I am getting the message: "Bummer! Your 'result' variable has the wrong value in it...

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

    return greeting
}

let result = greeting("Tom")

Quizes are not only about validating in Xcode but also to match answer Treehouse expect :)

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

    return (greeting, language)
}

Thanks, just realized they wanted greeting and language positions swapped. Here's how I did it:

Swift
func greeting(person: String) -> (greeting: String, language: String) {
    return ("Hello \(person)", "English")
}
let result = greeting("Tom")
