Can someone explain how this is wrong?

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

    return (language, greeting)
}

var result = greeting("Tom")

You forgot to name the tuples in your return statement.

 return (greeting:greeting, language:language)
