string is not returning, a little help with fizz buzz code

could anyone help me with this code?

func fizzBuzz(n: Int) -> String { // Enter your code between the two comment markers for n in 1...100 { if ( n % 3 == 0) && (n % 5 == 0) { print ("Fizz Buzz") } else if (n % 3 == 0) { print ("Fizz") } else if (n % 5 == 0) { print ("Buzz") } else { print (n) } }

// End code return "(n)"

}

fizzBuzz.swift
func fizzBuzz(n: Int) -> String {
  // Enter your code between the two comment markers
  for n in 1...100
  {
  if ( n % 3 == 0) && (n % 5 == 0)
  {
  print ("Fizz Buzz")
  }
  else if (n % 3 == 0)
  {
  print ("Fizz")
  }
  else if (n % 5 == 0)
  {
  print ("Buzz")
  }
  else 
  {
  print (n)
  }
  }

  // End code
  return "\(n)"

}

Looks like you pretty much got it, but you need to alter it for the challenge to accept it. You need to return the strings instead of printing them. And you need to get rid of the else clause, the challenge is taking care of that for you. The for loop that you used doesn't need to be there either. Also, there is no space in the string "FizzBuzz". So basically all you need to change is things that will make it accepted for the challenge. Your logic looks ok.

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"
  }

  return "\(n)"
}
