Apple announced a big change to how it names its operating systems at WWDC 2025 on Monday . Instead of using system names like iOS 19 and macOS 19, the company will now use the year as part of the name. This means all its operating systems will be called iOS 26, iPadOS 26, macOS 26, tvOS 26, watchOS 26, and visionOS 26.

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.
