A good CS education teaches common core concepts, and more importantly how to learn and adapt to new frameworks/environments quickly. Apple just doesn't want to deal with 2-4 months of ramp-up when they can have someone with expertise in a specific subject. Wealthy institutions see that, and teach certain frameworks as part of their graduates' education. Why else would you see core courses in languages like Objective C? Any graduate can learn it fairly quickly, but a common theme among employers these days is that they will invest nothing in employees.
