[opensource-dev] About memory management on macOS 10.12 (Sierra) potentially affecting all viewers

[Geir Nøklebye]

Apple is pretty predictable in how they announce changes to their code. Every summer, at the WWDC, they announce a slew of changes that will be introduced throughout the next year. They also announce deprecated technologies, which usually takes 3-5 years to completely be unsupported. 
They also often set some long term directions in the form of introduction of new platforms such as tvOS, technologies such as the Swift language, or changes of underlying hardware such as the change from Motorola 68k to PowerPC, and from PowerPC to Intel processors. 

That is the ebb and flow of developing for macOS (iOS is even a notch faster.) 

If your livelihood depends on customers paying for the platform you provide, and a portion of the paying customers accesses your platform via a macOS client, you better follow this ebb and flow, or it will eventually impact your bottom line. 

For the TPV developers, they probably could care less on the monetary aspect of it. 

Right now, perhaps the most profound long term technology direction is that Objective-C will completely be replaced by Swift in their codebase. https://swift.org
