"Some" is no longer showed in XCode for Optional types?

This is the exact code from the course:

func div (num1: Int, num2: Int) -> Bool? { if num1 % num2 == 0{ return true } else { return nil } }

however div(25,5) results in true not {Some true}. Why?

  • however println(div(25,5)) returns Optional(true) in the console.
