iOS Swift Functions and Optionals Functions Function Return Types

Why does this not work?

Im stuck on this one any help would be appreciated.

returns.swift
func greeting(person: String) -> String {
    let hello = println("Hello \(person)")
    return person
}
greeting("Tom")

It looks like you're just returning the value you sent to the function.

What are you hoping to do?

When you call the function, do you want it to return the greeting? If so, you should change your "hello" constant to equal a string saying "hello person", and return that.

When I run this in a playground it returns Hello Tom, but when I try to use it for the challenge it does not work. I'm not sure what I am doing wrong.

I figured it out thank you.
