Objective doesn't work

I copied out the "solution" into the objective and it turns out that even the solution provided by Pasan doesn't seem to work or be accepted?!

Make sure you follow step 3 of the instructions and replace your 'print' commands with 'return' commands.

switch true {
    case n % 3 == 0 && n % 5 == 0 : print("FizzBuzz")
    case n % 3 == 0 : print("Fizz")
    case n % 5 == 0 : print("Buzz")
    default: print(n)
}

This seems to work the same??

Thanks Pasan, I guess I am fighting with my own reading skills. Completed.

Did you follow the instructions in the challenge description? You can't copy the solution directly from the video into the challenge editor.

This doesn't pass the Treehouse test but works fine in my Playground. I am fighting with internet in China and have to deal with not only frustrating objectives but terrible connection. What's wrong with the code please? 

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

The challenge did not ask you to nest the code in a for loop. I mention in the video that I'm also just using the for loop to show you how the code behaves for many different values.

To pass the test just include the if else conditional code not the for loop

What do I have to write to return the number?

for n in 1...100{
    if (n % 3 == 0) {
        return "Fizz"
    } else if (n % 5 == 0) {
        return "Buzz"
    } else if (n % 5 == 0) && (n % 3 == 0){
        return "FizzBuzz"
    } else {
           return "\(n)"
    }
}

doesnt work

Marcel the for loop is not needed at all. Just the If statement. Also don't need the default case (else).

Thank you all for your feedback! The best answer was from Josue Gisber, just replace the word print with the word return and it should pass!

I was having a problem with the editor thinking that everything after the final " in the provided code was part of a string. Because of this, the solutions that worked in Xcode didn't work for this problem. I got around this by creating the following workaround. It's a lot of extra (and unnecessary) code, but if you run into the same problem I did and you really just want to check of the lesson then this might help.

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