It does look to me too as if the fruit have just not produced seeds for some reason....If it were mine I would probably just assume that the weather had not been right at the time and be grateful to get apples (I think I have 10 this year!). Were all your other apple varieties normal? Were the fruit smaller than usual?

In my (limited!) experience, apple maggots, codling moth, and core rot, common causes of core damage in apples, mostly leave brown debris, which your photo doesn't show.
