Why wont this work?

Why won't this code work? 

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

Try n = 15 and see if you get Fizz or FizzBuzz. If order is important you should check for FizzBuzz first. In addition to this as explained in the challenge this code is going inside a function - instead of print you should be using return

I think so Priority important if (n % 3 == 0) && (n % 5 == 0) { return "FizzBuzz" }

This was my solution and the compiler passes it without worrying about the order. I only check or cater for 3 conditions the teacher asked for. Would be nice if the teacher can comment!.

func fizzBuzz(n: Int) -> String {

  if (n % 3 == 0) && !(n % 5 == 0) {return "Fizz"} // for fizzBuzz() to return "Fizz" n should only be divisible by 3 this what it means 
  if (n % 5 == 0) && !(n % 3 == 0) {return "Buzz"} // for fizzBuzz() to return "Buzz" n should only be divisible by 5 this what it 
  if (n % 3) == 0 && n % 5 == 0  {return "FizzBuzz"} // here n should a divisible by both 3 and 5

  return "\(n)"
}

print(fizzBuzz(n:15)) // will print FizzBuzz
print(fizzBuzz(n:3)) // will print Fizz
print(fizzBuzz(n:5)) // will print Buzz
print(fizzBuzz(n:2)) // will print 2

Ah. It's the videos my phone objects to. I need a new one. If I'm on the laptop later, I'll have a look.
