I have doubt in FizzBuzz Question?

What's wrong in this code?

fizzBuzz.swift 
func fizzBuzz(n: Int) -> String {
  // Enter your code between the two comment markers
  import Foundation
var n = Int(arc4random_uniform(UInt32(150)))

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

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

Because your both your n%3 == 0 and n%5 == 0 are checked before n%3 == 0 && n%5 == 0 the third condition will never be checked. Any number it would be true for would also be true for the first condition, and return just "Fizz" instead of "FizzBuzz".
