Bummer! Double check your logic for Fizz values and make sure you're returning the correct string!

Why?! It works in the playground

fizzBuzz.swift 
import Foundation 
func fizzBuzz(n: Int) -> String {
  // Enter your code between the two comment markers
  let n = Int(arc4random_uniform(20))
if n % 3 == 0 { return "Fizz" }
else if n % 5 == 0 { return "Buzz" }
else { return "FizzBuzz" }
  // End code
  return "\(n)"
}

Hi Chris,

Try removing the following line:

  let n = Int(arc4random_uniform(20))

as n is supplied by the challenge.

Also, your fizzbuzz check needs amending as currently this would fire for values that are not a multiple of 3 or 5

The first condition in your if statement must be the fizzbuzz condition which is ((n % 3) == 0 & (n % 5) == 0) so that if the number is both divisible by 3 and 5 the fizzbuzz condition will catch it, and then the rest of the condition follows
