I dont know

What am I doing wrong here? The code works in Swift playground. But it will not be approved here ...

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) {
       return "FizzBuzz"
    } else if (n % 3 == 0){
        return "Fizz"
    } else if (n % 5 == 0){
        return "Buzz"
    } else{
        return n
}

Hi there! These challenges are very specific and because of the way that they are graded may have some unusual requirements. It seems that you missed the bottom line of the instructions:

The challenge also does not need you to loop over a range of values (using for or while). I'll take care of that.

Including a loop in your code will cause the challenge to fail. Instead of sending in a number and checking every value in that range for the output, it's going to send in several numbers one at a time, and check that the output was correct.

Hope this helps! :sparkles:

edited for additional information

Also, don't forget that a return statement will cause a function to exit. Because you are always starting with 1 here, and it does not fulfill any of the if or else if, it will return 1 and then stop. :smiley:

Thank you! Now it worked :)
