could someone help me with the Tuple task? I just don't get it

Currently our greeting function only returns a single value. Modify it to return both the greeting and the language as a tuple. Make sure to name each item in the tuple: greeting and language. We will print them out in the next task.

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

    return greeting
}

Hey Ferdinand Drobik !

So right now, it's only returning just a string, so in order to get it to return the tuple, we need to update two things:

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

    return (greeting, language)
}
  1. The return type in the function signature has to be changed from a String to a tuple.
  2. The return statement needs to be updated to be a tuple that includes the language.

Hope that helps!
