Functions As First Class Citizens Challenge

I got passed task 1, but I'm stuck on task 2.

Here is the error: http://i.imgur.com/Hwa4uHk.png

Hey, For part 2, i did this.

func printer(aString: String){
  println(aString);
}

let stringPrinter = printer
stringPrinter("hello");

This is because we want to assign the stringPrinter outside of the function. This will essentially create a reference to the function, which we can then use to pass in the variables. Assigning the stringPrinter inside of the function printer, is a topic known as recursion, which is outside of the scope of this course (at least so far).
