I thought it was this?

I'm confused... this: 

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

worked fine in playground. But when I add it to this challenge it doesn't work.

Hey there,

let's walk through this step by step. The corresponding assignments of this challenge are in brackets.

First of all, as your code is now supposed to be used within a function that already provides n you can get rid of this loop (You also don't need to define n. It is defined in the function provided):

for n in 1...100 {
   // ...
}

Secondly, the function is expected to return a String instead of printing to the console, indicated by -> String. (Change all your print statements to return statements. For example: print("FizzBuzz") becomes return "FizzBuzz")

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

Thirdly, "Buzz" and "Fizz" conditions are mixed up, they have to be changed to this:

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 {
        return ""
    }
}

This way, you should pass the challenge. Hope that helps :)

But functions weren't even taught before that challenge... functions were in the next course...

I only answered the question you asked in combination with the assignment you linked. This is out of context, so I did not know functions weren't covered yet. I am not responsible for the tracks here, just trying to help out ;)

You did help and thank you. I can easily do it now that I've started learning functions... maybe he wanted us to go back and do it? Anyway thank you again!
