iOS Swift Functions and Optionals Parameters and Tuples Tuples

This challenge is not letting me finish! I think I have the correct result, but it gives me an error.

I don't know what I'm supposed to do... I'm pretty sure I followed the instructions exactly, my code seems to be fine. If I copy this into Xcode and print variable "result" it prints the tuple perfectly.

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

    return (language, greeting)
}

var result = greeting("Tom")

OK, it turns out that the challenge requires the "greeting" constant to be the 1st part of the tuple, and the "language" constant to be the 2nd. Like so.

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

    return (greeting, language)
}

var result = greeting("Tom")

I think the challenge should be adjusted to accept both. It's unnecessarily frustrating not being able to complete the course because of something like this.
