How do you return a function that has a variable without using the println function to define the variable?

I'm trying to do the challenge for the function return and cannot figure out how to get my function to print out Hello Tom.

returns.swift 
func greeting(person: String) -> String {
    return "Hello greeting()"
}

Hello Mia,

You almost have it. 

func greeting(person: String) {
    println("Hello \(person)")
}

greeting("Mia")

Try placing the above code in playground to see it in action!

I'm still getting an error message. The point of the exercise is to take the println out of the code and replace it with return, but I must be getting the syntax wrong with the return. I have this:

func greeting(person: String) { return "Hello (person)" } greeting("Tom")

Mia, You don't need to add the greeting function it self.

only the following:

func greeting(person: String) {
    println("Hello \(person)")
}
