My code works perfectly in the playground. It's not compiling in your editor. I have replaced my print().

My code:

var n = 31 let fizz = "Fizz" let buzz = "Buzz"

if n % 3 == 0 && n % 5 == 0 { print("(fizz)" + "(buzz)") } else if n % 5 == 0 { print(buzz) } else if n % 3 == 0 { print(fizz) } else { print(n) }

I have removed all my variables/constants, added return "FizzBuzz". Still not compiling.

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

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

Nevermind. I took the add return "FizzBuzz" to literally. I added return "Buzz", return "Fizz" etc. and it worked.

The assignment asks you to return "FizzBuzz", "Buzz" or "Fizz" as a String, instead of printing it to the console. "FizzBuzz" is just one example of a return statement.

Step 3: Change all your print statements to return statements. For example: print("FizzBuzz") becomes return "FizzBuzz".

Therefore, the following should work:

func fizzBuzz(n: Int) -> String {
  if n % 3 == 0 && n % 5 == 0 {
        return "FizzBuzz"
    } else if n % 5 == 0 {
        return "Buzz"
    } else if n % 3 == 0  {
        return "Fizz"
    } else {
        // End code
        return "\(n)"
    }
}

P.S. Code that compiles in a playground has almost certainly no syntax errors, but that does not guarantee the correct result.

Hope that helps :)
