I believe this is correct but it keeps telling me it is wrong?

I don't understand what I am doing wrong

fizzBuzz.swift 
func fizzBuzz(n: Int) -> String {
  // Enter your code between the two comment markers
  for n in 1...100 {
    if (n % 3 == 0) && (n % 5 == 0) {
      print("fizzBuzz")
    } else if (n % 3 == 0) {
      print("Fizz")
    } else if (n % 5 == 0) {
      print("Buzz")
    } else {
      print (n)
    }

  }

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

Hi Justin. You're pretty close here. It looks like you've added an unnecessary for loop, causing your code to go through each number from 1 to 100 and print the results. Your function is setup to accept an integer to check against.

Step 3: Change all your print statements to return statements. For example: print("FizzBuzz") becomes return "FizzBuzz". You didn't change your print statements to return statements. So it's not going to return a result to the calling function.

Note: Do not worry about the default case (where the number doesn't match Fizz, Buzz, or FizzBuzz). You really don't need the default else case as a default value is returned if none of the other comparisons equate to tru. But, if you wish to keep it, you need to make sure a string is returned like it is formatted in the last return statement under the end code comment.
