Apple’s VP of Human Interface Design Discusses ‘Liquid Glass’ Approach for an Expressive and Responsive OS Inspired by visionOS

The phrase ‘Liquid Glass’ is etched in our memories, propelled by Apple’s frequent use of the term and the anticipation surrounding its integration across all company operating systems later this year. For users with an iPhone, the first experience of this innovative design interface can be explored through the iOS 26 beta 1. To understand the rationale behind this transformative approach, Alan Dye, Apple’s Vice President of Human Interface Design, reveals that Liquid Glass was selected due to its enhanced expressiveness and responsiveness, alongside several noteworthy attributes.

Apple’s Design VP Discusses Unseen Innovations and Industry Reactions

The reception of Liquid Glass has been varied, with some critics, including Samsung, taking a jab at Apple. Samsung’s assertion that its One UI 7 was a pioneer while suggesting that macOS 26 resembles Windows Vista illustrates the competitive landscape Apple is navigating. Nonetheless, TechRadar highlights insights from Alan Dye that shed light on the creative processes driving Apple’s decisions.

The last significant design shift occurred years back with the launch of iOS 7. Dye indicated that much of the work showcased during the WWDC 2025 keynote was influenced by visionOS. He explains that the transparency and visual effects associated with glass inspired thoughts on how to translate these qualities into software. However, Dye emphasizes the need for a dramatically different approach to the concept of glass in interface design.

Following hands-on experience with Liquid Glass, Dye observed that the interface exhibits heightened expressiveness and responsiveness, akin to the sensation of interacting with a physical liquid glass surface. He notes the lengthy duration required to develop this update, attributing it to the fact that 99 percent of their efforts remain behind the scenes, unseen by the public eye. Designing a user-friendly interface proves challenging, particularly when creating an operating system focused on simplicity.

Going forward, Liquid Glass is poised for further evolution, with the inaugural version expected to debut in the third quarter of 2025. As the rollout unfolds, updates across Apple’s various operating systems will soon follow, promising exciting transformations for users. Stay informed for upcoming developments.
