GlassEffectContainer

struct · iOS 26.0+ · SDK 27.1

@MainActor @preconcurrency struct GlassEffectContainer<Content> where Content : View

A view that combines multiple glass shapes into a single shape that can morph individual shapes into one another. You use a glass effect container with the ``View/glassEffect(_:in)`` modifier. Each view with a glass effect contributes a shape rendered with the physical glass material to a set of shapes. SwiftUI renders the glass effects together, improving rendering performance and allowing the effects to interact with and morph into one another. Configure how the glass shapes interact with one another by customizing the default spacing value provided to the container. As shapes near one another, their paths start to blend into one another. The higher the spacing, the sooner blending begins as glass approaches each other. In the example below, the two shapes render as if they are a single continuous shape as their geometries overlaps. private let viewSize = CGSize(width: 40.0, height: 40.0) GlassEffectContainer(spacing: value) { ZStack { Image(systemName: "pencil") .frame(width: viewSize.width, height: viewSize.height) .glassEffect() .offset(x: -(viewSize.width / 2.0), y: -(viewSize.height / 2.0)) Image(systemName: "note") .frame(width: viewSize.width, height: viewSize.height) .glassEffect() .offset(x: (viewSize.width / 2.0), y: (viewSize.height / 2.0)) } } }
