iOS Swift Functions and Optionals Optionals Review: Functions

How do I pass last challenge on optionals?

I was asked to writ another function and I copied the other one. I thought I did all they I was suppose to do, but I received this error...

You need to define a 'fun' named 'isNotDivisible' that takes a 'Int' parameter named 'dividend' and another 'Int' parameter named 'divisor' and returns a 'Bool"

What have I done wrong?

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

func isNotDivisible(dividend: Int, divisor: Int) -> Bool {
    reurn true  
    } else {
    return false 
}
