Apple has officially unveiled iOS 26 during its annual WWDC 2025 keynote, showcasing a major leap forward in both design and intelligence. This latest iPhone operating system brings a visually stunning new interface, smarter AI-powered features, and deeper system integration across apps and services. While the developer beta of iOS 26 is already live, the public beta is expected to arrive in the coming weeks. The final stable release is anticipated to roll out in fall 2025 alongside the new iPhone 17 lineup.

A Fresh Look: Meet the “Liquid Glass” UI in iOS 26

One of the standout features of iOS 26 is its brand-new visual design language known as “Liquid Glass.” This UI update introduces translucent system elements, fluid transitions, and depth-enhancing animations—bringing a more immersive and dynamic feel to iPhone. While the traditional iOS Home Screen layout remains intact, Apple has updated the appearance of menus, widgets, notifications, and the lock screen to make the user experience feel more modern and visually engaging.

Apps like Photos and Camera have also received layout overhauls, focusing on usability and visual consistency, aligning more closely with the look and feel of visionOS.

Apple Intelligence Gets Smarter in iOS 26

iOS 26 takes Apple Intelligence to the next level. This on-device AI system now powers a wide range of smart features designed to help users be more productive and expressive. Key AI features include:

  • Context-aware writing tools (rewrite, summarize, and proofread text)

  • Smarter message replies in iMessage and Mail

  • Real-time Genmoji and image generation

  • Personalized system-wide suggestions based on usage patterns

All of these features are designed to run locally on-device, keeping privacy and speed at the core.
