The question is asking you to return 2 strings instead of just returning a single single string. So after the "->" you want to return greeting and language both as strings. In order to do this you can do something like this

func sayHello(person: String) -> (welcoming: String, language: String) {
    let language = "English"
    let welcoming = "How is it going \(person)?"

    return (welcoming, language)
}

Does that answer your question?
