This doesn't make sense... I've inputed the necessary information, What else is there to input here?

I don't know what else to place in here...

What else do you need to place the code?

greeting.swift 
func greeting() {
  println("Hello")
}
greeting()

If the task asked you to modify the function and assign a parameter to it you would have done this 

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

then you call it greeting("Apple ") Therefore the result should be hello Apple. Hope that helps.
