Apple's Rare Concession: When Critical Vulnerabilities Meet the 'Update Refusal' Wave -- Fatbobman's Swift Weekly #130

A Swift developer newsletter covering two major iOS security threats (Coruna and DarkSword) that exploited watering hole attacks across iOS 13–18.7, prompting Apple's rare decision to backport security patches to iOS 18 via iOS 18.7.7. The update refusal wave, driven by iOS 26's Liquid Glass redesign and UK age verification requirements, left millions of devices vulnerable. The issue also curates SwiftUI animation internals via the Animatable protocol, SPM localization resource sharing across modules, a Coordinator-based navigation pattern, AI agent workflows for large dev teams, and a book on SwiftUI architecture patterns.
