Two things:

1) Your function signature states that it will return a string. Right now your if statement is printing the string. Change the print statements to return statements.

2) You don't need the for-in statement. Remove that. You can simply call the function by writing something like "fizzBuzz(n: 10)".

Here's the corrected code:

func fizzBuzz(n: Int) -> String {
  // Enter your code between the two comment markers
    if n % 3 == 0 && n % 5 == 0 {
      return "FizzBuzz"
    } else if n % 3 == 0 {
      return "Fizz"
    } else if n % 5 == 0 {
      return "Buzz"
  // End code
  return "\(n)"


Is it really supposed to be this complicated in just the second course of the track?

Should I go through some more basic level before I go on deeper in to this Swift track?
