What should I return ?

I'm not getting what I'm not returning correctly as it is telling me.

func fizzBuzz(n: Int) -> String {

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

Can I get a hand on this one ?

Thanks

Julien

fizzBuzz.swift 
func fizzBuzz(n: Int) -> String {

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

You don't need the loop, as the challenge said it would provide it (behind the scenes). You also don't want to print anything. Otherwise, it looks good, and you have the logic of it correctly:

func fizzBuzz(n: Int) -> String {

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