Hi folks,
Apple’s Optimize your app’s speed and efficiency digs into real performance challenges: long view body updates, unnecessary re-renders, and inefficient data flows. If you missed it live, Ilian Konchev captured comprehensive Q&A notes worth reviewing.
This week also brought 26.2 betas across all platforms, plus a fresh App Store web experience designed to make app discovery easier.
In this issue, we’re exploring SwiftUI gestures and animations, diving into performance optimization and compiler improvements, and uncovering practical patterns for form validation, localization, and platform-specific development.
