iOS Swift Functions and Optionals Parameters and Tuples Tuples

Stuck in part 2 of the Tuple-Challenge (your `result` variable has the wrong value in it)

This is my code, it works when pasted into xcode. But here I get an error and the message "...result variable has the wrong value in it ... read the instructions..."

Did I get the question wrong?

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")

You can both call greeting("Tom") or greeting(person: "Tom") since the function only receives one named variable but the problem is NOT there. ;-)

The exercise was asking to pass greeting first and then language in the tuple. That's all really, your code works but you switched the return elements in the tuple.

The second task says to "create a variable named result and assign it the tuple returned from function greeting". This is done like this:

var result = greeting("Tom")
