Wrap the button in GlassEffectContainerIOS26 and apply glassEffectInteractiveIOS26 with a shape such as Circle or a rounded rect. The interactive variant adds touch feedback, and the container ensures unified composition with sibling glass elements.

Place both elements in the same GlassEffectContainerIOS26, assign each a glassEffectIDIOS26 with a shared namespace, and animate the state change with .animation(.bouncy). Elements with matching IDs morph smoothly instead of appearing abruptly.

The utilities handle version checks internally. On iOS 26 and later they apply native glass effects, while earlier versions fall back to Color.Background.navigationPanel combined with ultraThinMaterial blur.

Use GlassContainerViewIOS26 to group elements and GlassEffectViewIOS26 for individual interactive glass views. Always add your buttons to glassContentView rather than directly to the glass view, and call shape methods like applyCircleShape once during setup.

The glass effect defines its own shape through the shape parameter, so a separate clipShape call is redundant and can produce incorrect rendering. Pass the shape directly to glassEffectIOS26 or glassEffectInteractiveIOS26 instead.

Glass effects are intended only for the navigation layer and floating controls, not for content. Text and content views should use standard backgrounds such as Color.Background.primary instead of glass modifiers.
