Tuple confusion

The Tuple concept is confusion following the video. I feel as if I may have added the paramaters in the function properly, but maybe not (line 1). But I'm not sure what else to do. Please advise.

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

    return (language: String, greeting: String)
}

You dont need to tell the compiler that the returned values are strings as you have done this when you construct the function.

Return this return (language, greeting)

var result = greeting("Tom")
println("English")
