Edit: I looked at what you wrote again and understand what you were looking to do. Although I'm not clear as to why println isn't accepting it. Nevertheless find the answer below.

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

greeting()

Thanks for the answer! I actually started off doing something similar to this, but didn't call the greeting after the function, which caused it to error, and that was why I tried alternatives. When getting a proper error message I thought it was easier to debug, but all I did was making the function more complicated haha.

Anyway, thanks a lot!
