(Don't Fear) The Reaper

Next week Apple WWDC 2019 will likely begin the transition to an entirely new UI framework for macOS. This article does a good job putting that in context and looking at the last time that happened, when NeXT OPENSTEP was in the mix.

In 2007, Apple got the chance for a complete do-over of Mac OS X with a modern architecture optimized for touchscreen devices with powerful GPUs, but with thermal, resource, and battery constraints. That do-over was, of course, iPhone OS. […]

With macOS 10.15, UIKit is finally coming back to the Mac to serve as a top-tier native application development framework alongside AppKit. This is the start of Apple's next transition, and just like last time, it's almost unfathomably difficult to see how these two completely different architectures will cooperate and find common ground.

I think this will be a fun ride. 🎢
