What am I doing wrong in this Tupel exercise? The code outputs perfectly in xcode

Here is the code:

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

    return (greet, language)
}

I've watched the videos 5-6 times and I'm still not seeing what I should. They exercise wants me return the language and the greet in the tuple.

the task states: Make sure to name each item in the tuple: greeting and language. so you need to name the elements of the tuple in your return type

                                          //give the tuple elements a name
func greeting(person: String) -> (greeting: String, language: String) {
    let language = "English"
    let greeting = "Hello \(person)"

    return (greeting, language)
}
