Apple's documentation was actually vastly superior before Swift. In fact, I often refer to the documentation "archive" instead of the latest docs. The decline in the docs is due to a number of factors, but I would say mainly it's (1) the relentless annual major OS update schedule, (2) the proliferation of OS (macOS, iOS, watchOS, tvOS, xrOS?), (3) the dual language stack, (4) Apple personnel turnover.
