iOS Swift Functions and Optionals Parameters and Tuples Tuples

I think my code is right, but it's not working (iOS/Dev/Swift/tuples). Any thoughts?

The challenge is to create a variable named result and assign it to the tuple return values of the function, and the challenge notes that I should pass the string "Tom" to the function. I wrote:

var result = greeting("Tom")

but the code is rejected. This code works in Xcode. Am I reading the question incorrectly?

Thanks

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

    return (language, greeting)
}

var result = greeting("Tom")

task 1 states: Make sure to name each item in the tuple: greeting and language.

so, while it let you pass the first task, it seems like it expects greeting to come first, then language. modify your code so that greeting is first and language is second in the tuple:

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

    return (greeting, language)
}

var result = greeting("Tom")

Hi Tim,

You problem is with the ordering of your return statement variables. I have tested this theory with the question as well. You are correct in that your code works in Xcode but not in Treehouse.

Cheers, Daniel.
