The first issue of a new newsletter, Apple UI Insider, is out: a field guide to Apple's UI rendering stack, Core Graphics, Core Text, Core Image, Core Animation, and SwiftUI. Every picture in it is drawn twice, once by my clean-room renderer, once by Apple's own frameworks, with the differences measured and published. That check caught a real bug: two renders disagreeing by 3.9%, traced to one coordinate flip, fixed to 0.07%. #SwiftUI #AppleDev https://aleahim.com/blog/apple-ui-insider/

I recently launched http://SwiftUIArchitecture.com Over the years, I've come across many excellent articles, WWDC sessions, videos, books, and open source projects about SwiftUI architecture. Instead of letting those resources get lost, I wanted to put them all in one place. The site is a curated collection of high-quality SwiftUI architecture resources that I personally recommend. I'll continue adding new resources as I discover them. I hope you find it useful. #SwiftUI #iOSDev #AppleDev
