Apple is set to unveil major design overhauls across its operating systems at WWDC 2025, according to Bloomberg's Mark Gurman. iOS 19, iPadOS 19, macOS 16, tvOS 19, and watchOS 12 will all feature new designs, inspired by the visionOS interface for the Vision Pro headset. The changes aim for greater consistency, particularly between iPadOS and macOS, enhancing multitasking and productivity on iPads. Gurman anticipates these design updates, codenamed "Solarium," to be WWDC's main attraction, overshadowing even AI-related announcements.
