"reporting bugs doesn't benefit the developer at all. It benefits Apple."

If Apple fixes the bugs how does it NOT benefit me, the developer? The fewer bugs there are the easier development is. Reporting a bug may be helping Apple but that is secondary to helping myself.

Does the benefit from the view of pure self-interest help you understand better why someone might do something that has direct benefit to themselves?

The summary of your attitude is contained in the old phrase "Cutting off the nose to spite the face".

Also, as far as not being an employable skill - I make my whole living from it currently (currently using Swift only), generally iOS has been an employable skill since the release of the App Store so again, you seem to be waving that knife way too close to your nostrils.
