# SwiftUI Liquid Glass Use native Liquid Glass APIs for the requested surface; do not convert unrelated UI or add glass merely because an app uses SwiftUI. Read [references/liquid-glass.md](references/liquid-glass.md) for API patterns and examples. Verify uncertain availability against the installed SDK and Apple documentation. - Match the project's deployment target and provide fallback when older OS versions are supported. - Group related glass surfaces with GlassEffectContainer where needed. - Apply glass effects after relevant layout/appearance modifiers; make only genuinely interactive surfaces interactive. - Use glassEffectID and namespaces when a requested transition needs morphing, not as a universal requirement. Preserve existing behavior and design intent. For review-only work report findings; for implementation inspect the affected rendering and interaction on supported targets.
