Hi Atharv,

Your function header looks good. As for replacing the println statement, you can specify the string you want to return in the actual return statement.

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

Hope this helps!

Sorry CJ Marchione.. but it didnt quite work.. :/
