iOS Swift Functions and Optionals Optionals Review: Functions

I wrote the code using Xcode it shows that it is correct but in your screen it is giving me an error

func isNotDivisible(dividend: Int, divisor: Int) -> Bool { if dividend % divisor > 0 { return true } else { return false } } let result = isNotDivisible(15,5) if result == true { println("Not Divisable") } else { println("Divisable") }

divisible.swift
func isNotDivisible(dividend: Int, divisor: Int) -> Bool {
    if dividend % divisor > 0 {
        return true
    } else {
        return false
    }
}
let result = isNotDivisible(15,6)
if result == true { println("Not Divisable")
} else {
    println("Divisable")
}

This is the answer that worked for me:

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

} else {
    return true
    }
   }
