Use when implementing iOS 26 features (Liquid Glass, new SwiftUI APIs, WebView, Chart3D), deploying iOS 26+ apps, or supporting backward compatibility with iOS 17/18.

.claude/skills/ios-26-platform/# 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](references/liquid-glass.md)** | Implementing glass effects, choosing Regular vs Clear variants, or understanding visual properties | | **[Automatic Adoption](references/automatic-adoption.md)** | Understanding what iOS 26 changes automatically vs what requires code | | **[SwiftUI APIs](references/swiftui-apis.md)** | Using WebView, Chart3D, `@Animatable`, AttributedString, or new view modifiers | | **[Toolbar & Navigation](references/toolbar-navigation.md)** | Customizing toolbars with spacers, morphing, glass button styles, or search | | **[Backward Compatibility](references/backward-compat.md)** | Supporting iOS 17/18 alongside iOS 26, or using UIDesignRequiresCompatibility | ## Core Workflow 1. **Check deployment target** — iOS 26+ required for Liquid Glass 2. **Recompile with Xcode 26** — Standard controls get glass automatically 3. **Identify navigation layer** — Apply glass to tab bars, toolbars, navigation (not content) 4. **Choose variant** — Regular (95% of cases) or Clear (media-rich backgrounds only) 5. **Add @available guards** — For backward compatibility with iOS 17/18 6. **Test accessibility** — Verify Reduce Transparency, Increase Contrast, Reduce Motion ## Common Mistakes 1. *
