With limited exceptions, platform vendors (Microsoft, IBM, Sun/Oracle, etc) are generally not in the business of paywalling their development documentation, tools, and SDKs, otherwise it makes their platform far less attactive to third-party developers that they absolutely need in order to.
...and ever and never-mind that Apple's documentation is sub-par[1], even with the billions of dollars they're raking in. It boggles the mind because nothing is stopping Apple from hiring the people it needs to ensure decent documentation and DX, which can be paid-for directly from the $99/yr developer membership fee.
