What is wrong with my code here?

I used the function to greeting and gave it the string Tom so it should return greeting and language, but it is saying that I am doing this wrong. Can someone explain?

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

    return (language, greeting)
}

var result = greeting("Tom")
println(result)

Your code is perfectly alright!

In the assignment, however, you are asked to return greeting first. Swap the return values in the tuple and adjust the return statement accordingly:

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

    return (greeting, language)
}

var result = greeting(person: "Tom")

Although you passed the first task, code check seems to be picky when it comes to the returned tuple in the second task.
