FizzBuzz

Ok,

What am I doing wrong here. Keep in mind I have been trying to solve this for 3 days. I am using the exact same syntax that is in the answer video. Which I almost came up with on my own forgot the "for n in 1...100" part. But my issue is I am getting the error: "Bummer! Double check your logic for Fizz values and make sure you're retuning the correct string!"

Using the following code:

fizzBuzz.swift 
func fizzBuzz(n: Int) -> String {
  // Enter your code between the two comment markers

    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)
    }
    // End code
  return "\(n)"
}

Hey Yashim,

You're probably going to kick yourself when I tell you what's wrong...

With the actual code, you have nothing wrong. However, you missed one vital instruction for the challenge: "Step 3: Change all your print statements to return statements. For example: print("FizzBuzz") becomes return "FizzBuzz". You still have print statements.

And while it will pass with the final else statement, the challenge also specifically says to not include it, as a final return is provided.

Have a look :)

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"
    }
    // End code
  return "\(n)"
}

Keep Coding! :dizzy:

I tried approaching the problem over a couple of days with a Case statement:

func fizzBuzz(n: Int) -> String {

    for (n) in 1...100 {
        switch n {
        case n % 3 == 0: return "Fizz"
        case n % 5 == 0: return "Buzz"
        case n % 3 == 0 && n % 5 == 0: return "FizzBuzz"
            // End code
        }
    }

    return "\(n)"
}

I got a Bool issue, but aside from that, what is the advantage of using an IF statement over Case?

nb. I know I don't have a "default"
