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.

Apple's 2026 operating systems will be unified and see a major visual upgrade called the Liquid Glass design language.

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.
