Apple is set to unveil a significant design overhaul for iOS 19, affecting the iPhone, iPad, and Mac later this year. Reports suggest that this update will enhance user experiences by refreshing icon styles, menus, and system buttons, aiming for a consistent aesthetic across devices. Bloomberg indicates that the redesign will be the most substantial since iOS 7 and macOS Big Sur. Notably, the project, codenamed 'Luck,' is expected to focus on key apps like the Camera and Siri. Announcements are anticipated during WWDC 2025.
