iOS 26 introduces Liquid Glass, Apple's next-generation material design system that dynamically bends light, moves organically, and adapts automatically across all platforms.
iOS 26 modernizes UI with new materials (Liquid Glass), SwiftUI APIs (WebView, Chart3D, @Animatable), and advanced features (@BackoffAnimation, free-form windows). The core principle: modern UI gets updated automatically at compile time; most Liquid Glass benefits are "free" from recompiling with Xcode 26.
ALWAYS load reference files if there is even a small chance the content may be required. It's better to have the context than to miss a pattern or make a mistake.
Da utilizzare durante l'implementazione delle funzionalità di iOS 26 (Liquid Glass, nuove API SwiftUI, WebView, Chart3D), la distribuzione di app iOS 26+ o il supporto della compatibilità con le versioni precedenti con iOS 17/18. Fonte: johnrogers/claude-swift-engineering.
