CACountInteractor contains business rules

[DivineDominion]

I'm talking about this part:

- (void)decrement
{
    if ([self canDecrement])
    {
        --self.count;
        [self sendCount];
    }
}

Shouldn't the Interactor delegate to a model object in the domain? I know this would be tedious since the call to increment would be delegated yet another time. But that's the deal, isn't it?

The Interactor should contain application-dependent business logic. Entities (i.e. model objects) would contain application-independent business logic.

However, you are right to point out that it might be better to use a model object. I plan to expand this example in the future to include the use of an Entity.
