cannot complete first Swift function challenge even if done correctly

The error checker does not work. It warns me that I need to enclose the println function inside a function, which I did.

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

If this error is happening on the first task, it's probably because you've added the line to call the function afterward. The error checker can be very literal and you can get errors if you add any more code than the question asked for!

Sara is right.

You have to complete the challenge tasks in order. You can't just put in the finished code on task one or else you get the error " Bummer! You shouldn't call println directly. It needs to be in the body of the function.".

This can also crash and cause the page to need to be reloaded.
