Apple has always been famously anti-developer. They write terrible documentation, too. You're supposed to suck up to them to get access to their precious users.

Everything in this article is a reason to stay away from everything proprietary about Apple development. If there is some software that can't be delivered with open web technology or an existing game engine, I'd like to know what it is.

Old Apple, the one before NeXT reverse acquisition, had great documentation.

FWIW, I've been developing on the mac for about twenty years now, and I think they're at worst in the middle of developer experiences. I prefer it to working with eg GTK and JS/HTML/CSS (though, CSS does have its sweet spots). The worst part is that they can be agonizingly slow to fix very obvious bugs. The documentation could certainly be much worse, and there are so many eyes on their tools now it's in many ways much easier now to be productive than it used to be. The debugging and profiling is excellent.

I've never trued developing for windows so I could easily imagine it's better across the board.

It also helps if you don't need to go through their app stores, which is a hell of its own.
