Apple Liquid Glass: How the New Software Design Works
Liquid Glass is Apple’s translucent, adaptive interface material introduced across its 2025 operating-system updates, including iOS 26, iPadOS 26 and macOS Tahoe 26.
Timeline
- June 9, 2025: Apple previewed Liquid Glass and iOS 26 at WWDC25.
- 2025 software releases: The design extended across Apple’s major operating systems and built-in apps.
Liquid Glass is Apple’s name for the translucent interface material introduced with its 2025 software design. It is a visual and interaction system, not a physical screen coating. Apple says the material reflects and refracts surrounding content while changing with context, movement and the elements beneath it. [1][2]
Apple applied the design across iOS 26, iPadOS 26, macOS Tahoe 26, watchOS 26 and tvOS 26. The shared treatment gives controls, navigation, app icons and system surfaces a related appearance while allowing each device category to preserve its own input methods and layout needs. [1][2]
On iPhone, the design changes visible layers such as the Lock Screen, Control Center, tab bars and toolbars. Navigation elements can float above content, and tab bars may contract while a person scrolls before expanding when needed. These behaviors are intended to leave more room for the content underneath. [1][2]
Liquid Glass does not by itself describe every feature in iOS 26. Live Translation, updates to Phone and Messages, and changes to visual intelligence were announced alongside the redesign, but they are separate capabilities. The term specifically refers to the new material, styling and related interface behavior. [1]
For developers, many standard SwiftUI, UIKit and AppKit components adopt the new appearance when apps are built with current tools. Apple also provides APIs for custom elements, but its guidance emphasizes standard components, clear hierarchy and careful use so overlapping translucent surfaces do not reduce legibility. [2]
The effect can vary with wallpaper, content, light and dark appearance, and accessibility settings. That variability is part of the material’s design: it is meant to adapt rather than behave like one fixed color. Screenshots from different devices can therefore show different tint, contrast and reflections while using the same system. [1][2]
Liquid Glass is best understood as the foundation of a broader Apple interface update. It creates visual continuity between devices and gives developers a common set of behaviors, while individual apps still decide their information structure and controls. Installing a supported operating-system release brings the system design; app-specific adoption can vary. [1][2]
