You should return, not print. So the correct code is: 

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)"
}
