There is a decent amount of convergence in game development, since Sprite Kit has SKView, SKColor, etc. (whose base classes vary by platform but most methods are the same) and important frameworks like AVFoundation are identical.<p>The Mac has shown hints of iOS influence when looking at recent changes to NSViewController and the addition of other standard view-controller-based classes.<p>Realistically, though, I like Apple&#x27;s separate-but-similar approach.  I don&#x27;t <i>want</i> Mac applications shoehorned in from iOS by lazy developers, I want applications that were actually written for the desktop.
