I've been rewriting my code through Apple System 6->System 7->System 8/9->Carbon->OS X->PPC to Intel->iOS. Honestly most of my memories dealing with Apple have been deprecation and rewrites. Every time Apple touts some new technology, I think to myself that they'll be sunsetting it in 5 years or whatever. I'm coming to terms with nearly the entirety of the code I wrote the last 24 years being useless. I highly recommend to anyone getting started in software development to only use open source and cross platform tools. My own theory for why most software projects can only reach a million lines of code is that this is the limit of entropy. Think of it as, what's the largest boat that you can safely bail out with a bucket of water? Your apps will be quite a bit smaller on Mac OS than say, Windows or Linux, or else you'll find yourself keeping up with changes more than making stuff. And I don't believe deprecation is a necessary evil to innovate or pivot. Apple could and should do much better in this department.
