iOS Swift Functions and Optionals Functions Creating a Function

I'm pretty sure this exercise is wrong.

I put:

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

greeting()

I got an error saying that I can't just call println directly because it has to be enclosed in a function for this exercise. It is. I would put "Hello" as a parameter, but func parameters hasn't been introduced yet in this course.

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

greeting()
