How should I proceed?

How should I proceed with the code?

I thought just changing the "return greeting" to "return (greeting, language)" would do it, but apparently not.

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

    return greeting
}

Hello Ceonn Bobst :

Well, you were on the right track, but you are missing something else. 

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

    return (greeting,language) // Your suggestion ?
/*
   altho this is correct, you have to see your method signature.
   Your method signature says that you are going to return a string,
   but you need to return 2 strings. Which is a tuple. 
*/

}

I don’t really want to give you straight up answer, because it may help you more to try to figure it out on your own with some help. BUT if you can’t figure it out, Ill be more than happy to explain with details.
