iOS Swift Functions and Optionals Optionals Review: Functions

How do I adjust the function isNotDivisble to work with isDivisible? Optionals, functions, tuples, and bool are possible

The challenge gives me a lot of repeated information but how do I repeat variables and function terms and keep them working.

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 {
  if dividend % divisor == 0 {
    return true
    } else {
      return false
      }
}

if let result = isNotDivisble(dividend: 4, divisor: 3)
  println("Divisible")
  } else {
    println("Not Divisible")
}

Hello Roderick Royce :

This is the answer you should have. Please notice the comment inside the function

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

func isNotDivisible(#dividend: Int, #divisor: Int) -> Bool {
    if dividend % divisor == 0 {
    return false // here should be false since it’s not divisible 
} else {
    return true  
    }
}
