I think that it has some legal reasons, cause when a third party framework developer fucks the whole system, Apple gets bad press and must wait for the third party dev to fix the thing. But if there is something wrong with an framework from Apple, they can just fix it in very short time with an OS update. (Thats my personal opinion and nothing from the dev Forum and/or the Beta SDK!)
Yes, this is what Steve Jobs wrote in some of his emails. But is there a good framework from Apple? Is there any game engine from Apple, physics layer, sound engine, collision detection, scene management? Or is each developer now doomed to program its own system from scratch? Is this the step back to the middle age of programming? Back to the pointers, memory allocators and pointers to pointers to manage stacks, get rid of good garbage collection and powerful function libraries?
