I can't get the code to run. I get an error message stating I can't run Println directly with or without constant use.

These are the functions I've tried:

func greeting() {
  let hi = "Hello"
    println(hi)
}
greeting()

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

Its worth noting that both run fine in Xcode. I am using the Safari browser on Mac.

If you're on the first question, they aren't asking you to call greeting() yet, so just delete that for now. This is all you need for the first task:

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

Are you trying to call greeting() in Task 1? You second function is correct, but the Challenge throws that error if you try to call greeting() outside of Task 2.

Thanks, Bryan. Clearly trying run while the challenge was asking me to walk :-) I don't know how I missed that in the question.

Best, Pete
