Hi Alan Buckley , what you need to do is to change the return format, so you can return a tuple instead of a single value. On your function parameters you do not have to change anything, just receive the person name. The return type is what you have to change to a tuple, code should look like this:

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

    return (language, greeting)

Hope that helps you

Thanks David. Well appreciated
