shouldn't call println directly?

why is happening this to me?

greeting.swift
func greeting() {
  let greet = "Hello"
  println(greet)
  } 
greeting()

It is looking for the simplest solution:

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

That will get you through the challenge.

Steve.

You then call it with

greeting()

as you have correctly done.

Thanks for the help Steve, but sorry, the error keeps it same. I don't have idea where is the mistake...

Weird! Can you paste your code again, or screenshot it?

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

Right - Task 1 requires just:

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

Submit that the first task ... then add the next line for Task 2.
