Glass effects in SwiftUI are implemented using the glassEffect modifier and GlassEffectContainer, both available in iOS 26+. Wrap your views with these modifiers and guard them using #available(iOS 26, *) to ensure compatibility. Provide a non-glass fallback for earlier iOS versions to maintain consistent UI across all supported devices.

Use GlassEffectContainer with SwiftUI's built-in morphing transitions on surfaces, buttons, and cards. The container handles shape consistency and applies glass aesthetics while managing interactive state changes. Ensure availability checks and test fallback rendering on iOS versions below 26.

Glass effects require iOS 26 or later. For older versions, you must implement a fallback UI using standard SwiftUI components like regular backgrounds or opacity effects. The #available guard ensures your app compiles and runs safely on all iOS versions you support.

Review views for correct glassEffect and GlassEffectContainer application, consistent shape usage across components, and proper #available(iOS 26, *) guards with non-glass fallbacks. Validate that morphing transitions and interactivity work as expected on supported iOS versions while fallbacks render correctly on earlier versions.

Liquid Glass effects work best on single views and container-level components like surfaces and cards. Complex nested hierarchies may require refactoring for consistent glass appearance. Performance depends on morphing transition complexity; test on target devices to ensure smooth rendering at your target frame rates.

Liquid Glass is built into iOS 26+ and requires no external dependencies. You need only SwiftUI and the native glassEffect modifier and GlassEffectContainer APIs. Ensure your project targets iOS 26 as the minimum version or higher to access these native APIs.
