Blocked at last challenge of second swift module

Modify the definition of the function named greeting to return a String and replace the println statement with a return statement. The function should return a greeting. For example, if you pass in a string "Tom" then the return string would be: "Hello Tom".

I can't figure out the code, the one I did doestn work and I feel like I tried everything...

Thanks for your help in advance !

returns.swift 
func greeting(person: String) {
    return greeting
}

  println("Hello  \(greeting("Tom"))")

Just Switch the println with return. (To have the function to return a value you have to "Modify the definition of the function " with "-> String" (to return a string).

You are not asked to do anything else in the challenge.

This should work:

func greeting(person: String) -> String { 
    return ("Hello \(person)")
}
