Hi Daniel,

A tuple is a way to return multiple values. So, in the exercise, you have to do 2 things : • return both the greeting and the language • name the return values

Here is the code that works for that :

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

    return (greeting, language)
}
