Unable to get my code to wotk o FizzBuzz challenge in swift 2.0

The code works in xcode

for count in 1...100 { if (count%3 == 0) && (count%5 == 0) { print("FizzBuzz") } else if (count % 3 == 0){ print("Fizz") } else if (count % 7 == 0) { print("Buzz") } else { print(count) } }

however I am not able to translate it correctly for the challenge...please help someone!

fizzBuzz.swift 
func fizzBuzz(n: Int) -> String {
  // Enter your code between the two comment markers
    if (n % 3 == 0) && (n % 5 == 0) {
        return "FizzBuzz"
    } else if (n % 3 == 0) {
        return "Fizz"
    } else if (n % 7 == 0) {
        return "Buzz"
    } else {
        return "\(n)"
    }
  // End code
  //return "\(n)"
}

Hi Nad

The reason your code is working in Xcode and not in the challenge is because your code is actually correct, although it isn't the answer for the challenge as the TeamTreeHouse compiler checks for.

When checking for the "Buzz", you should check for the remainder of 5 not 7, so the code should look like this instead

func fizzBuzz(n: Int) -> String {
  // Enter your code between the two comment markers
    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)"
    }
  // End code
  //return "\(n)"
}

This code is working - hope it helps

I did not realize the "FizzBuzz" if statement had to run fist. Thanks for this!
