How do I write this code

I'm trying to write a simple function code. It's saying I can't call on the println directly. It needs to be inside the body.

greeting.swift 
func greeting() {

let right = "Hello"

println("right")
}


greeting ()

Hey there,

I think you're overthinking it a bit by assigning "Hello" to a constant which you don't really need to. However if you do, you have to remove the quotes around "right" in your println function because right now you're printing out the String "right" instead of the right constant.

If you print it out without an extra constant it should look like this:

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

greeting()

Also note that in Swift 2 println became deprecated and that you have to use print now.

I hope that helps! :)
