Using case statement does not work

What is the issue when using case statement for FizzBuzz?

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

Hey man, this logic is what worked for me on this one:

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

put that in between the comments and it should work :)

Thank you. Yes, I know using the 'if' statements resolves the challenge. However, I wanted to get it working with 'case' statement.

The switch method entails more code and unreadability, so it's feasible that Pasan hasn't accepted this answer to encourage more elegant code. If you have a way that works, use it :)
