While the new software updates that Apple showed off today are only available to developers at the current time, Apple does plan to release

The first developer betas for iOS 26, iPadOS 26, watchOS 26, tvOS 26, visionOS 26, and macOS Tahoe are dropping today if you’re eager to try many of the new features and updates that Apple just announced.

So as of 2025, all of Apple's OSes are named after the year they'll mostly cover. So after iOS 18 comes iOS 26, and after watchOS 11 comes watchOS 26, rather than iOS 19 or watchOS 12, as we initially assumed. The one small exception is macOS 26 Tahoe, which still gets its California-inspired name alongside its number.
