Swift functions parameters and tuples

My answer seems to evaluate correctly in my playground and the feedback about my return value is too ambiguous. What is wrong with my answer?

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

    return (language, greeting)
}

var result = greeting(person: "Tom")

Your tuple is the wrong way around. It needs to be greeting then language.

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

    return (greeting, language)
}

var result = greeting(person: "Tom")

Not sure why the task runs like that but I guess it has to do with how TeamTreeHouse checks the answer.
