527 PointsFizzBuzz working in Xcode, not Treehouse
I ran this code in Xcode, with print("") instead of return as instructed in the tasks. This seemed to give the intended result in the debugger---i.e. 1,2,Fizz,4,Buzz. But still not working in the Treehouse console. So, I'm wondering what I am missing here.
func fizzBuzz(n: Int) -> String {
// Enter your code between the two comment markers
var n = 0
while n >= 0 {
n += 1
if (n % 3 == 0) {return "Fizz"}
if (n % 5 == 0) {return "Buzz"}
if (n % 15 == 0) {return "FizzBuzz"}
else {return n}
}
// End code
return "\(n)"
}

Python Development Techdegree Graduate 29,026 PointsI believe the reason it's not passing in the treehouse compiler is because the return value in the else of the modulo conditionals is an Int as opposed to the expected return value of String, outlined in the function. I don't understand why you've gone for a while loop and redeclared n as 0? You don't have numerous int's to iterate over, nor different scenarios that a conditional can't deal with?
I've simplified your code below, seems to work and passes the challenge ok - hope this helps!
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"
}
// End code
return "\(n)"
}
