Code Challenge Error

What's wrong with this code challenge (step 2)?

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

   var result = greeting("Tom")
   return result

}

Both values language and greeting need to be returned. Working example:

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

    return (greeting, language)
}

What you're doing is recursion. You're calling greeting within greeting, then returning that as the result. What the challenge wants you to do is, store the value outside of the function greeting (below it). What good is this variable if we can't access it outside the scope of the greeting function.

I do recommend you use the Preview tab with when doing the Swift videos, it helps a lot.
