I am unsure what is wrong with my code

It says to check my FizzBuzz code but I can't see anything wrong with it, can you help?

fizzBuzz.swift 
func fizzBuzz(n: Int) -> String {
    // Enter your code between the two comment markers
    if n % 3 == 0 {
        return "Fizz"
    } else if n % 5 == 0 {
        return "Buzz"
    } else if n % 3 == 0 && n % 5 == 0 {
        return "FizzBuzz"
    } else {
    }
    // End code
    return "\(n)"
}

Hi Isaac,

Test for the double-test first else you'll filter out all your FizzBuzz candidates at your first test. Other than that, lose the last, empty, else statement and your code is fine.

Like this:

  // Enter your code between the two comment markers
    if n % 3 == 0 && n % 5 == 0 { // do this first!! 
        return "FizzBuzz"
    } else if n % 5 == 0 {
        return "Buzz"
    } else if n % 3 == 0 {
        return "Fizz"
    }
  // End code

Steve.
