ABOUTME: iOS 26+ Liquid Glass API for glassmorphism effects and interactive UI ABOUTME: .glassEffect() modifier, Glass variants, tint, interactive glass, containers, fallbacks SwiftUI Liquid Glass

API verified against Apple's SwiftUI documentation (2026-07). If a parameter is not listed here, do not guess it: fetch the current docs for View.glassEffect(_:in:) and Glass.

When to Invoke

• iOS 26+ glassmorphism effects
• Frosted glass backgrounds
• Translucent interactive UI
• Modern iOS 26 aesthetic

The Real API

nonisolated func glassEffect(
    _ glass: Glass = .regular,
    in shape: some Shape = DefaultGlassEffectShape()  // capsule by default
) -> some View

Glass is a configuration struct, NOT an enum of styles:

Member	Declaration	Purpose
.regular	static var regular: Glass	Standard Liquid Glass material
.clear	static var clear: Glass	Clear variant
.identity	static var identity: Glass	No-op variant (content unaffected)
.tint(_:)	func tint(Color?) -> Glass	Returns a tinted copy
.interactive(_:)	func interactive(Bool) -> Glass	Returns an interactive copy (responds to touch)

There is NO intensity: parameter, NO GlassEffectStyle, NO interactive: label on glassEffect itself. Configuration composes on the Glass value.

Basic Usage

@available(iOS 26, *)
struct GlassCard: View {
    var body: some View {
        VStack {
            Text("Liquid Glass")
            Text("iOS 26+")
        }
        .padding()
        .glassEffect()  // .regular, in a capsule
    }
}

Custom shape and composed configuration:

content
    .glassEffect(.regular.tint(.blue.opacity(0.2)), in: .rect(cornerRadius: 16))

Button("Tap Me") { ... }
    .padding()
    .glassEffect(.regular.interactive(true))

With Fallbacks

struct AdaptiveGlassView: View {
    var body: some View {
        if #available(iOS 26, *) {
            content.glassEffect()
        } else {
            content.background(.ultraThinMaterial)
        }
    }

    var content: some View {
        Text("Works on all iOS versions").padding()
    }
}

GlassEffectContainer

GlassEffectContainer combines multiple Liquid Glass shapes into a single shape and can morph individual shapes into one another. Use it when several glass elements sit close together or animate between layouts; give elements a glassEffectID(_:in:) within a shared @Namespace for morphing transitions.
