Challenge confusion...

In this challenge I am asked (below)... any help would be largely appreciated, side notes too if any as they would help me understand and learn it better :) Thanks

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".

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