Every year, iOS is one of the star attractions of Apple 's Worldwide Developers Conference keynote. It's our first official look at new features and other changes that are coming to iPhones in the fall. The 2025 WWDC keynote was no exception, and the most immediate change is to the iOS naming system.

Apple has unveiled iOS 26, the next version of its iPhone operating system, as part of its suite of announcements at its Worldwide Developers Conference (WWDC). It features a complete redesign with Apple’s new “Liquid Glass” design language.

Apple has introduced Liquid Glass in its upcoming iOS 26 update. Liquid Glass provides a "see-through" visual of a glassy surface throughout iOS 26's interface. The liquid part comes into play with how the see-through visuals adapt to the screen depending on what the user is doing.
