The code runs in Xcode

The code for this challenge runs in Xcode without any error, but says incorrect in the challenge, and I am having some trouble finding what is actually wrong. I tried changing things around a bit but it still didn't quite work for some reason. Thanks.

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

    return (greeting, language)

What did the challenge ask you to do? This is returning two Strings after modifying one of them with the parameter the function takes.

This returns a tuple. So,


returns a tuple of .0 "Hello Steve", .1 "English"

This can be accessd in dot notation such as; greeting("Steve").0 is "Hello Steve" and greeting("anystring").1 is "English".
