Getting multiples of a value in swift

Question

I am trying to check if a number is a multiple of 3 or 5 or both in which different vaues would be printed. I am able to get the values running but checking for both does not seem to give the expected result.

here is my code and response

func fizzBuzz(n: Int) -> Void {
    let value = n
    for i in 1...value{
        if(i.isMultiple(of: 5)){
            print("Buzz")
        } else if(i.isMultiple(of: 3)){
            print("Fizz")
        } else if (i.isMultiple(of: 5)) && (i.isMultiple(of: 3)){
            return print("FizzBuzz")
        } else {
            print(i)
        }
    }

}

fizzBuzz(n: 15)

the response

1
2
Fizz
4
Buzz
Fizz
7
8
Fizz
Buzz
11
Fizz
13
14
Buzz

Simply that is it's multiple of BOTH, then the first if will be triggered before triggering the dual check. Check firstly if it's mutliple of both. — Larme, Nov 11 '19 at 11:09
Also, checking for both multiples of 3 and 5 identical to checking if it's multiple of 15 — user28434'mstep, Nov 11 '19 at 11:18

Check first multiple of both

func fizzBuzz(n: Int) -> Void {
    for i in 1...n {
        if i.isMultiple(of: 15) {
            print("FizzBuzz")
        } else if i.isMultiple(of: 5) {
            print("Buzz")
        } else if i.isMultiple(of: 3) {
            print("Fizz")
        } else {
            print(i)
        }
    }
}

fizzBuzz(n: 15)

`isMultiple` is already part of standard library in Swift 5 – user28434'mstep Nov 11 '19 at 11:41
@user28434 you are right :) https://developer.apple.com/documentation/swift/int/3127688-ismultiple – Cruz Nov 11 '19 at 11:48

Here is the answer based on the above.

func fizzBuzz(n: Int) {

    let value = n

    for i in 1...value {

        // The number is multiple of 3 and 5
        if (i.isMultiple(of: 15)) {
            print("FizzBuzz")
        }
        // The number is multiple of 5
        else if(i.isMultiple(of: 5)){
            print("Buzz")
        }
        // The number is multiple of 3
        else if(i.isMultiple(of: 3)){
            print("Fizz")
        }
        else {
            print(i)
        }
    }
}

fizzBuzz(n: 15)
