at the event. Now a report by Bloomberg’s Mark Gurman suggests that this major UI overhaul will serve as a precursor to the

, expected to launch in 2027. The new iOS 26’s interface is said to be inspired by VisionOS and is said to introduce translucent elements, floating menus, and a seamless glass-like aesthetic across Apple’s ecosystem. This development, expected to be a highlight of WWDC 2025, signals a profound shift in Apple's hardware and software integration strategy.

WWDC 2025: iOS 26’s Liquid Glass design

The Liquid Glass interface marks Apple’s biggest design shift since iOS 7, featuring sheen, transparency, and layered depth effects. The goal is to create a UI that feels fluid and reflective, mirroring the futuristic aesthetics of Apple’s Vision Pro. Menus, toolbars, and notifications will reportedly gain a dynamic, transparent visual style, enhancing user interaction with layered depth effects and context-aware translucency. This aesthetic is part of Apple's broader "Solarium" interface language.Liquid Glass will extend beyond iOS 26, influencing macOS, iPadOS, watchOS, and tvOS, ensuring a cohesive design language across Apple’s devices.

The 20th-Anniversary iPhone: ‘Glasswing’ concept

As reported by Gurman, this "Liquid Glass" design is more than just a visual upgrade; it is strategically built to support Apple's future hardware, particularly an upcoming iPhone model internally codenamed "Glasswing." This device, anticipated for the iPhone's 20th anniversary in 2027, is rumoured to feature an unprecedented design.

The 20th-anniversary iPhone is expected to boast curved glass sides that wrap around the entire phone, including its edges, creating a seamless, all-glass enclosure. Furthermore, it is speculated to feature extraordinarily slim bezels and a truly edge-to-edge screen with no front-facing cutout, implying the integration of under-display Face ID and camera technologies.
