Hey guys, I don't understand why This isn't passing. Any tips?

Hey guys, I don't understand why This isn't passing. Any tips?

My answer is almost identical to the video, all ive done differently is change the print to return like instructed too.

fizzBuzz.swift 
func fizzBuzz(n: Int) -> String {
    for n in 1...100 {
        if (n % 3 == 0) && (n % 5 == 0) { return "FizzBuzz"
        } else if (n % 3 == 0) { return "Fizz"
        } else if (n % 5 == 0) { return "Buzz"
        } else {
        return }
        }

Hi Jordan - You are missing the final return

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

Also why does n have quotation marks in final return? Shouldn't it be return(n) ?

Hi Jordan - Yes I have an app on the App Store, it is called wrench conversions. It has a pickerView and picks a standard wrench size and gives you the metric equivalent.

As for your other questions, it has the quotations around it because it is a string. If you try to submit it without them you will get an error because you cannot convert string to Int or something like that
