How do I return 'language' and 'greeting' as a tuple?

I can't seem to make it work on this. I am able to do it in my playground. Can you give me a hint?

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

    return (greeting,language)
}

You'll want to specify the return value as a tuple in the declaration, i.e. -> (language: String, greeting: String)

This is correct, but wasn't present or clear in the video. http://sht.tl/aAojNL (screenshot of video)

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

Figured it out. Thank You!!
