I don't understand what's wrong with my function?

I think I did everything right. Could someone take a look at it please?

Hi Ruslan,

Your code didn't attach; could you please copy and paste it here?

Hi Ruslan,

For this Challenge, you can actually just copy and paste the first function and tweak it a little; add a "Not" to the name, and change == 0 to != 0.

func isNotDivisible(#dividend: Int, #divisor: Int) -> Bool {
    if dividend % divisor != 0 {
        return true
    } else {
        return false
    }
}

Please let me know if you have any questions about why that works!

I typed the whole code by myself and it didnt accept it... But then i refreshed the page and just changed the name of the function and the equal sign. The problem is in the system. But thanks for trying to help!
