Hi, as far as I remember they want you to return multiple values by using tuples, so you should rewrite the function to return a tuple of values:

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

    return (greeting, language)
}
