Pixel perfect is dead, long live to adaptive and accessible iOS apps
summary
Asserts that pixel‑perfect layouts fail on modern iOS and shows concrete fixes: migrate from hardcoded 320-by-480 points to Auto Layout/constraints and size classes, support 12 different text sizes and 11 Dynamic Type styles, flip stack axis or swap constraint sets for large fonts, use readableContentGuide and scalable PDF images, and prefer system colors or provide darker variants so contrast moves from 2.2:1 to 7.3:1. Demonstrates Xcode previews and the Accessibility Inspector, gives a 30% adoption stat for user text-size changes, and shows these techniques working across UIKit and SwiftUI.
