func fizzBuzz(n: Int) -> String {

// Enter your code between the two comment markers

```for n in 1...100 {

if (n % 3 == 0) && (n % 5 == 0) {

return("FizzBuzz")

} else if (n % 3 == 0) {

print("Fizz")

} else if (n % 5 == 0) {

print("Buzz")

} else {
}

return "\(n)"

}
```

}

// I don't know what I'm doing Wong? Can someone help?

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) {
print("Fizz")
} else if (n % 5 == 0) {
print("Buzz")
} else {
}

return "\(n)"
}
``` You 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)
``` func fizzBuzz(n: 100) -> Int {

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("\(n)")

}

}

return n
```

}

// something like that ? You 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.
