I pasted the code in playgorund and got the result "Hello Tom" but i keep getting an error saying wrong value.

I keep getting an error saying result was passed the wrong value. I am getting the result "Hello Tom" with zero errors when I copied this code in playground. Can someone point out my mistake. Thanks.

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 are on the right track ,I think the return should be greeting then language but you have the inverse..

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

              return (greeting, language)
         }
                 var result = greeting(person: "Tom")

You've done everything right, except it was expecting the result tuple values to be the other way round. See below:

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

    return (greeting, language)
}

var result = greeting(person: "Tom")

Just swap the positions of greeting and language.

Thanks guys. Was this just Treehouse being picky or is there a reason it must go in this order?
