FizzBuzz question.

new to swift Hello all I've been stuck on the FizzBuzz question, I've known from the beginning that I could either use if statment or switch and after trying many different things and piecing other examples from the web I got 

func fizzbuzz(n: Int) -> String {
    switch (n % 3 == 0, n % 5 == 0) {
    case (true, false):
        return "Fizz"
    case (false, true):
        return "Buzz"
    case (true, true):
        return "FizzBuzz"
    default:
        return String(n)
    }
}

However this works in the playground but when submitting as my answer it says its incorrect. If anyone can help it will be greatly appreciated :)

Formatted Johns code to make it easier to read.

func fizzbuzz(n: Int) -> String {
    switch (n % 3 == 0, n % 5 == 0) {
        case (true, false): return "Fizz" 
        case (false, true): return "Buzz" 
        case (true, true): return "FizzBuzz" 
        default: return String(n)
    }
}

Your code for the switch statement is correct there is just one little problem with your function. The "b" in your function fizzbuzz is not CAPITALIZED that is why your code probably did not work. This is late but I wanted to figure out why your code didn't work :)

John, Did you try implementing this without the function code - just as the switch statement? If that doesn't work it could be related to the way you set up the Switch statement on tuples (very creative by the way...).

I think they are looking for you to use if/in statement to iterate through a given range, instead of creating a function.

Here is an example

for n in 1...100 { if (n % 3 == 0) && (n % 5 == 0) { print("FizzBuzz") } else if (n % 3 == 0) { print("Fizz") } else if (n % 5 == 0) { print("Buzz") } else { print("(n)") }}

(I can't find the original question so I might be totally off-base...)

Hi, I tried this one in playground and worked but couldn't submit it in to challenge form. any ideas?

func fizzbuzz( n: Int) -> String {

switch n {
case _ where n % 3 == 0 && n % 5 == 0 : return "FizzBuzz"
case _ where n % 3 == 0 : return "Fizz"
case _ where n % 5 == 0 : return "Buzz"

default: return String(n)
}

return " \(n)" //Will never be executed (xcode warning)

}

fizzbuzz(15) //FizzBuzz
