Apple is preparing a comprehensive redesign of its major operating systems, including iOS, macOS, iPadOS, watchOS, and tvOS, to be unveiled at the Worldwide Developers Conference (WWDC) scheduled for June 9-13, 2025. The redesign, internally referred to as 'Solarium,' aims to introduce a unified and consistent visual language across the Apple ecosystem, inspired by VisionOS. This overhaul will feature more transparency, crystalline effects, new icons, and changes in app navigation, extending beyond iOS and macOS to platforms such as watchOS and tvOS. Alongside the software updates, Apple is expected to launch the iPhone 17 series in September 2025, including the iPhone 17 Air and iPhone 17 Pro. The iPhone 17 Pro is anticipated to have an evolutionary design update with 12 new features and may represent a strategic shift from its predecessor. Rumors also suggest that Apple plans to redesign the iPhone annually through 2027, culminating in a model with curved glass. Additionally, Apple is reportedly testing a 200-megapixel camera sensor for future iPhone models, a notable upgrade from the current 48-megapixel sensors, although this camera is not expected to debut on the iPhone 17. Other anticipated hardware improvements include the potential under-screen placement of Face ID and the selfie camera by the time of the iPhone 19 release. The watchOS 12 update is also expected to introduce three new features for the Apple Watch. Overall, WWDC 2025 is poised to showcase a major software design revamp and set the stage for upcoming hardware innovations in Apple's product lineup.
