再见，iOS 19！你好，iOS 26

Core Viewpoint - Apple is restructuring its six major operating systems (iOS, iPadOS, macOS, watchOS, tvOS, and visionOS) by adopting a new naming convention that uses the year as a suffix instead of traditional version numbers, aiming for better consistency and clarity for users and developers [1][3]. Group 1: Naming Convention Changes - The new naming strategy will see the next iOS version announced at the 2025 Worldwide Developers Conference (WWDC) referred to as iOS 26 instead of iOS 19, aligning with a model similar to the automotive industry [1]. - This adjustment is intended to unify the version numbers across different systems, which currently vary due to their initial release dates, causing confusion among users and developers [3]. Group 2: User Interface Overhaul - A significant user interface redesign, codenamed "Solarium," is set to be the largest in Apple's history, focusing on a glass-like aesthetic for visionOS and extending to tvOS and watchOS, aiming for a cohesive visual language across devices [3]. - The redesign is expected to provide a smoother and more modern user experience, enhancing the transition between different Apple devices [3]. Group 3: New Features in iOS 26 - iOS 26 will introduce a new feature on the lock screen that displays an estimated time to full charge for the device, addressing a common user pain point of guessing charging times [5][6]. - Although this is a minor feature, it is considered practical for users, as iPhones have not previously provided accurate charging time information [6].
