What do I need to do to complete this challenge task?

I don't understand what I need to do to complete this challenge task.

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

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

Hi Jordan,

You're simply missing the Int type from your divisor parameter, simply add that and your code will pass.

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

Happy coding!

Chris answer is correct, also I think you missed the returning Bool value as an optional

-> Bool?
