Question broken?

The starting code fails to evaluate without edits in the editor on the site. Xcode has no problem evaluating the code, however. It complains about a missing curly brace???

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

I'm not sure what was wrong here. I hard-refreshed the page and everything worked fine.

You forgot to finish the question, you need to add a function isNotDivisible which is the opposite of is divisible. 

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

It just shows that because I refreshed the page. When I had the content shown in the paste, it was still failing to evaluate. There was some problem with the editor... Nevermind!
