So there're 3 issues here.

  1. the printl in line 2 is misspelled, the correct form is println.
  2. when calling the function in line 5, func keyword is not needed, as the function has already been defined.
  3. you need to pass in the person label when calling the function.
func greeting(#person: String)  {
    println ("Hello \(person)")
}

greeting(person:"Jerry")

Hope it helps. Cheers.
