Error is println should not be called directly, it should be in body of function. But it is (I think) ;-) Works in playground just not on treehouse site...
func greeting() { let halo = "Hello" println("(halo)") }
greeting()
func greeting() {
let halo = "Hello"
println("\(halo)")
}
greeting()

Courses Plus Student 26,865 Pointswhat's the error? I see no error from this code of yours.

2,012 PointsI think it's an error in the compiler or whatever is checking the code when I do the test in a browser. It's happened before and thrown me into looking for solutions when code was ok... thx for checking ;-)

2,012 PointsOK so here's the error I get in a 'red' panel...
Bummer! You shouldn't call println directly. It needs to be in the body of the function.

func greeting() {
println("Hello")
}
greeting()
Then you don't have any issues.

Courses Plus Student 26,865 Pointsactually, if you try copy/paste his code to challenge, it'll pass. His code got no problem at all, I think his only mistake is to copy everything over, including the last line greeting(), which part 1 of challenge didn't expect and thus cause error.

13,515 PointsThat is it. The first part of the two challenges never asks for the greeting function to be called "directly" hence the error "don't call println directly".
