@leocg iOS 26 is named that way to align the operating system's version number with the calendar year of its release, specifically, the 2025-2026 release cycle. This change, also applied to other Apple operating systems like iPadOS, macOS, watchOS, and tvOS, simplifies the naming convention and aims to create consistency across all platforms. Instead of having different version numbers for different operating systems, all will now be named based on the year they are released.
