Challenge Task 2 of 3 seems to be broken for this course

What's going on here?

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

    return (language, greeting)
}

var result = greeting("Tom")

You need to swap greeting and language:

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

    return (greeting, language)
}

var result = greeting("Tom")

In the assignment greeting is the first part of the tuple, language the second.

Make sure to name each item in the tuple: greeting and language

Admittedly, that is not too obvious and the fact that you can pass the first task either way is making it even more confusing.

Hope that helps, though :)

Wow, that ended up being the problem. Thanks Martin!
