FizzBuzz challenge error compiling code

I first got the error code "Double check your logic for Buzz values and make sure you're returning the correct string!" and found an answered question that said that I do not need the ´´´ for n in 1...100 ´´´ part of the code, so I removed that part and now it doesn't compile. Not sure what went wrong

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

  for n {
    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)"
}

You need to remove your loop entirely. You have just removed the in 100 part of the condition for the loop, which is not enough and results in your code being invalid.

Like this:

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)"
}
