RZAffirm adds ease of implementation and clarity of intent to your assertions. RZAffirm defines functions which - like comments - express intent, but never go out of date. RRZAFFIRM_TRUE, RZAFFIRM_FALSE, RZAFFIRM_NOT_NIL, and RZAFFIRM_NONEMPTY_STRING all do exactly what you think they do.

RZAffirm includes more exciting assertions that come in handy in a variety of contexts. For example:

You define a method on a class, but you want that method to ONLY be called by subclasses. Use RZAFFIRM_SUBCLASSES_MUST_OVERRIDE to throw an exception if the method is called from the class itself:

class RZSuperclass

func aMethodThatShouldBeCalledFromSubclassesOnly -> Void {
  RZAFFIRM_SUBCLASSES_MUST_OVERRIDE(self);
}

You define a switch statement with a case that should never occur. Use RZAFFIRM_SHOULD_NEVER_GET_HERE to throw an exception if your program passes the undesired case to the switch statement:

enum AwesomeMode {
    case AwesomeModeNotSet
    case AwesomeModeIsAwesome
}

func configureThingsForAwesomeMode(awesomeMode:AwesomeMode) -> Void {
    switch awesomeMode {
        case .AwesomeModeNotSet:
            RZAFFIRM_SHOULD_NEVER_GET_HERE(self)
            break
        case .AwesomeModeIsAwesome:
            break
    }
}
