iOS 26 Platform
iOS 26 introduces Liquid Glass, Apple's next-generation material design system that dynamically bends light, moves organically, and adapts automatically across all platforms.
Overview
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.
Reference Loading Guide
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.
| Reference | Load When |
|---|---|
| Liquid Glass | Implementing glass effects, choosing Regular vs Clear variants, or understanding visual properties |
| Automatic Adoption | Understanding what iOS 26 changes automatically vs what requires code |
| SwiftUI APIs | Using WebView, Chart3D, @Animatable, AttributedString, or new view modifiers |
| Toolbar & Navigation | Customizing toolbars with spacers, morphing, glass button styles, or search |
| Backward Compatibility | Supporting iOS 17/18 alongside iOS 26, or using UIDesignRequiresCompatibility |
