Use when building features with TCA (The Composable Architecture), structuring reducers, managing state, handling effects, navigation, or testing TCA features. Covers @Reducer, Store, Effect, TestStore, reducer composition, and TCA patterns.
Use when implementing iOS 17+ SwiftUI patterns: @Observable/@Bindable, MVVM architecture, NavigationStack, lazy loading, UIKit interop, accessibility (VoiceOver/Dynamic Type), async operations (.task/.refreshable), or migrating from ObservableObject/@StateObject.
Use when writing async/await code, enabling strict concurrency, fixing Sendable errors, migrating from completion handlers, managing shared state with actors, or using Task/TaskGroup for concurrency.

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.
| 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 |
Ignoring backward compatibility — Targeting iOS 26+ without @available guards breaks iOS 17/18 support. Always use if #available(iOS 26, *) for Liquid Glass or new APIs.
Over-using glass effect — Applying glass to content areas, not just navigation, creates visual noise. Glass works for: tab bars, toolbars, sheets, navigation. NOT for content areas.
Animation performance issues — Liquid Glass animations can be expensive. Respect Reduce Motion accessibility setting and profile with Instruments 26 before shipping.
Assuming Clear variant looks good — Clear is for media-rich backgrounds only (photos, video). Regular variant is correct 95% of the time. Only use Clear if you explicitly need the ultra-transparency.
Not testing on actual devices — Simulator rendering differs from hardware. Test glass effects on iPhone 15 Pro, iPad, and Mac to verify visual quality.
Using old UIView patterns with new glass — Mixing UIView-based navigation with iOS 26 glass creates inconsistent appearances. Migrate fully to SwiftUI or wrap carefully with UIViewRepresentable.
