There are several ways to solve this

  1. You correctly laid out your IF statements, the problem is you have the incorrect values in there. I would suggest going back and watching the video when Pasan explains the task. You need to check the FizzBuzz values first or the rest of the IF statement will give incorrect results (this is where most individuals make a mistake when they are tested with this question for employment. You then simply check the other two values. Also yo are missing the final ELSE clause in your code. The structure is correct you just need to focus on the values :) Hope that helps!
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")
    } else {
        return("n")
    }
    // End code
}
