# Can someone Help me ? (Swift)

Hi there,

I am stuck on this challenge and i don't know what i am doing wrongThis is my challenge: Given the isDivisible function, create another function called isNotDivisible which also takes in two parameters, namely the dividend and the divisor. It should also return a Bool. The goal of this new function is to let you know whether a dividend is NOT divisible by the divisor. (Note: the function should return only a Bool and not an optional.) This is my error: Bummer! You need to define a func named isNotDivisible that takes a Int parameter named dividend and another Int parameter named divisor and returns a Bool. -Note- There are also a few errors in my code itself.

Thank you for your help!

divisible.swift
```func isDivisible(#dividend: Int, #divisor: Int) -> Bool {
if dividend % divisor == 0 {
return true
} else {
return false
}
}

func isNotDividible(#dividend: Int, #divisor: Int) -> Bool {
let sol = (divident % divisor) {
if let sol == 0
return true
}
return false
}
```

This challenge is actually super easy. Your implementation of `isNotDividible` function should be nearly identical to `isDivisible` provided by the challenge. Because these 2 functions are doing the exact opposite things.

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

You see, In the `isNotDivisible` function, all I did was swap the truthiness of the return value from the `isDivisible` function, and that's all there's to it.

Hi William,

It worked and now i get how to do it. I was actually surprised how easy this is.

Thank you very much!

An even easer way that requires only on character change for the entire function is to just change,

`if dividend % divisor == 0` from the isDivisible function to

`If dividend % divisor != 0` for the isNotDivisible function.
