tested locally and result variable is returning the correct tuple values. What's the issue here?

not sure what I am missing in my code?

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

return (language, greeting)
}

var result = greeting("Tom")

Oh i see.. change the order of the tuples and the order in which they are being returned. Not sure why it matters but that should work. Let me know. Here is what i have in case you still don't get this to work: 

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

    return (greeting, language)
}

var result = greeting("Tom")

Also read that you can try naming your return values:

return (language: language, greeting: greeting)

Let me know which worked for you.

That did it! I simply changed the order in which the tuples were being returned. I am also not sure why this matters or not. Must be something they would need to look into as part of their code validation logic in the course.

Thanks again!
