Apple will usher in a major change, not only to integrate the user interface experience, but also to name the operating system with the year. iOS 19 and macOS 16, which everyone was familiar with, will become "iOS 26" and "macOS 26" in one fell swoop next year, and even watchOS and tvOS will all be renamed. What's more, Apple's AI system "Apple Intelligence" is also ready to be opened to third-party developers, and more apps will be integrated into Apple's AI system in the future. Apple's system naming logic has been changed from "version number" to "year" According to reports, Apple intends to completely change the "year naming system" to the new system launched in the fall of 2025, such as iOS, iPadOS, macOS, watchOS, tvOS, and visionOS will all become "26", which represents the 2026 version. That is, iOS 18 becomes iOS 26, macOS 15 becomes macOS 26, and so on.
