iOS Swift Basics (retired) Control Flow Exercise: FizzBuzz Generator

Parentheses

Hey I succeeded at making the FizzBuzz generator heres my code: 

for number in 1...20 {

if number % 3 == 0 && number % 5 == 0 {

        println ("FizzBuzz")

    } else if number % 5 == 0 {

        println("Buzz")

    } else if number % 3 == 0 {

        println("Fizz")

} else {

    println(number)
}
}

I saw that Amit put parentheses around his ( i % 3 == 0) however it worked for me without. Is it a good habit to put parentheses around it?

Hi, Anthony Paulino I've edited the code format for you.

Is it a good habit to put parentheses around it?

The parentheses are optional in this case, so whether to use them is largely a matter of personal preference. But IMO, I'd say that wrap the boolean condition around with parentheses makes the code a bit more readable; also, if you're unsure about operator precedence, it's good idea to use parentheses to be on the safe side.
