You aren't wrong. Objective-C is dying. The huge machine that nursed the frail, nearly-forgotten language back to health -- and then pumped it full of steroids and made it a monster -- has been disconnected, and hooked up to Swift, instead. Apple's bet on Objective-C was the only thing that made it broadly relevant -- but now they have moved on, and Apple is generally the type of company that does the opposite of "support both forever". I agree that it is dying very slowly, however. You will probably still be able to write OS X apps in Objective-C in 2020, albeit with various caveats.
