## Welcome to the Treehouse Community

The Treehouse Community is a meeting place for developers, designers, and programmers of all backgrounds and skill levels to get support. Collaborate here on code errors or bugs that you need feedback on, or asking for an extra set of eyes on your latest project. Join thousands of Treehouse students and alumni in the community today.

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

fizzBuzz.swift
```func fizzBuzz(n: Int) -> String {
// Enter your code between the two comment markers
for i in 1..100 {
if (i % 3 == 0) && (i % 5 == 0) {
print("FizzBuzz")
} else if (i % 3 == 0) {
print("Fizz")
} else if (i % 5 == 0) {
print("Buzz")
} else {
print(i)
}
}
// End code
return "\(n)"
}
```

There are a few things in the instructions that weren't followed.

1) Change your variable/constant name that you are checking in each step to `n`

2) Change all your print statements to return statements

3) Do not worry about the default case

4) The challenge also does not need you to loop over a range of values

So it works now? Here is your code updated that passed for me:

```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)"
}
```
