is this a better or worse way to make the FizzBuzz generator?

for i in 1...20 {
    if i % 3 == 0 {
        print("Fizz")
    }
    if i % 5 == 0 {
        print("Buzz")
    }
    if i % 5 != 0 && i % 3 != 0 {
        print(i)
    }
    println()
}

I am using the print() function in stead of the println() function to make the "Buzz" stand behind the "Fizz".

My code looks like:

func fizzbuzz(#number: Int){
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("No fizzing, buzzing, or fizzbuzzing for you!")
}
}

I then tested it with a loop:

for var i = 0; i < 50; i++ {
    fizzbuzz(number: i)
}

I hope that helps.

Steve.

May I also add the one addition:

for i in 1...20 {
    if (i % 3 == 0) && (i % 5 == 0) {
        print("\(i) - FizzBuzz")
    } else if (i % 3 == 0)  {
        print("\(i) - Fizz")
    } else if (i % 5 == 0) {
        print("\(i) - Buzz")
    } else {
        print("\(i) - Null")
    }
}

This lets you see each number for a bit more clarity.
