So true. I've been working on my iOS app for about 4 years now, and recently started work on porting it to the Mac. But it's so much more tedious than I expected, for exactly the reasons you mention: lack of documentation and support, lots of subsystems to work on, legacy controls that aren't customizable. Attending WWDC and talking to people on both AppKit and UIKit teams, it's striking how little they seem to collaborate; it's like they live in their own organizational bubbles, and there is very little push from on top to make them more streamlined. They have made some progress on some frameworks to consolidate them across Mac OS and iOS (MapKit comes to mind), but it feels like they still operate as two independent entities within Apple; one being the young hot-shot with all the resources, and the other being the envious legacy-system that knows it's past it's best.
