SwiftUI Is One Graph, Over 40+ Years of Engineering.

I measured the real framework until its behavior was predictable, then read Apple's granted patent. They agree, almost field for field: SwiftUI is one demand-driven graph, and the least interesting engine in the stack it rests on.

The marvel is underneath: Core Animation, by John Harper, Apple's Carmack and Torvalds, who almost no one can name. Start of a series.

Seriously, this "stupid autocomplete that just predicts tokens" understands and explains AppKit and Core Animation better than probably most iOS devs would… that's good enough for me ¯\_(ツ)_/¯

I finally found a reason to use my scrolling marquee that I made for Music Widget, QuickTune, etc. etc. for an iOS app...

My PDX Transit SwiftUI re-write!!! Check it out:

(still a work in progress but you get the idea!)

#swiftui #coreanimation #trimet #portland #pdxtransit

I wrote the scrolling marquee using Core Animation for my apps but a while back, I found some issues where the text would look blurry on non-retina displays.

Unfortunately I found a few more cases (still happening a lot less than before), but finally found the issue and fixed it.

The top image has the blurry text (in the titlebar), and the bottom image has it fixed. 🛠️😄

Text now appears super sharp on non-retina displays and have yet to see a blurry example.

#QuickTune #UIUX #CoreAnimation

I just posted a sample project to GitHub which has the code I wrote for the Brushed Metal background in QuickTune.

It seems performant but I am probably not the best in determining if it is at its most performant. Seems good though.

This is done in Core Animation layers & good for both 1x and 2x displays.

I hope to see more Brushed Metal interfaces soon 😉
