I am curious as to why this is not working.

I am very confused about this challenge. How do I "win" the challenge. And this code doesnt work that I found after seeking help in the internet.

fizzBuzz.swift 
func fizzBuzz(n: Int) -> String {
  // Enter your code between the two comment markers
  for i in 1 ... 100 {
    switch (i % 3, i % 5) {
    case (0, 0):
        print("Fizz Buzz")
    case (0, _):
        print("Fizz")
    case (_, 0):
        print("Buzz")
    default:
        print(i)
    }
}
  // End code
  return "\(n)"
}

Pay attention to the instructions here. You're doing 2 things that the challenge specifies you shouldn't, and not doing 1 that you should. To pass this challenge, you need to:

  1. Operate on the parameter n that's provided
  2. return n as a String instead of print(n)
  3. Make sure you're only operating on n and not looping over any values

If you follow those rules, I believe your code will pass the challenge
