What's wrong?

I think I'm very close. Why is the FizzBuzz logic incorrect?

fizzBuzz.swift 
func fizzBuzz(n: Int) -> String {
  // Enter your code between the two comment markers


    if n % 3 == 0 {
    return "Fizz"
    }

    if n % 5 == 0 {
    return "Buzz"
    }

    else (n % 3 == 0 && n % 5 == 0) {
    return "FizzBuzz"
    }

  // End code
  return "\(n)"
}

Hi Erik,

  • Since you're specifying logic for your else, I'll use else if instead of else.

  • I would write the clause with the multiple conditions first. The reason for this is that any 'n' that divides without a remainder into both 3 and 5 will, therefore, also print something for the if statement that only checks for 3, and the one that only checks for 5. Since we're looking for "Fizz", "Buzz", or "FizzBuzz", and not "FizzFizzBuzz" or "BuzzFizzBuzz":

    if (n % 3 == 0 && n % 5 == 0) {
      return "FizzBuzz"
    }

    else if (n % 3 == 0) {
      return "Fizz"
    }

    else if (n % 5 == 0) {
      return "Buzz"
    }

Hope this helps!
