20,594 PointsYou have a few different things going on here...
First of all, your function should return an Int, not a String.
Next, you want to print("FizzBuzz"), not return it.
You're also missing a closing brace at the end, but that was because you had the return declaration in the wrong part. Here's the correct code...
func fizzBuzz(n: Int) -> Int {
for n in 1...100 {
if (n % 3 == 0) && (n % 5 == 0) {
print("FizzBuzz")
} else if (n % 3 == 0) {
print("Fizz")
} else if (n % 5 == 0) {
print("Buzz")
} else {
print("\(n)")
}
}
return n
}
And to call the function:
fizzBuzz(n: 100)

// something like that ?

20,594 PointsYou don't want to return the "Fizz" and "Buzz". You need to return n to the main function for the input variable. You need to print "Fizz" and "Buzz". Also when declaring a function, you don't put in your variables value. When declaring the function, it should read n: Int.
Your code should look exactly like the code I provided.
