Apple's iOS updates are always a subject of intense speculation and excitement, but the upcoming iOS 19 promises something truly groundbreaking. Codenamed "Solarium," this update is anticipated to bring the most significant aesthetic overhaul to the iPhoneâs operating system since the flat design revolution of iOS 7.

The Clues Hidden in a Codename
The term "Solarium" traditionally refers to a room constructed largely of glass to allow ample sunlight. This codename, revealed by Bloomberg's Mark Gurman, cleverly hints at the new design ethos for iOS 19: a glass-like, translucent interface. This shift suggests a move towards interfaces that blur the line between digital content and the userâs environment, offering a more immersive and visually engaging user experience.A Peek at the New Design
Leaks and rumors about the specifics of this new design have been circulating, with tech analyst Jon Prosser sharing renders of what the Camera and Messages apps might look like on his YouTube channel, Front Page Tech. These renders showcase interfaces with a more translucent feel, enhancing the visual depth and aesthetic fluidity of the apps. However, despite these leaks, there remains a healthy debate regarding the scope and execution of these design changes.
Historical Context and Expectations
The last time Apple undertook such a bold redesign was with iOS 7, which marked a departure from skeuomorphism to a cleaner, flatter design language that has dominated iOS aesthetics ever since. Gurmanâs insights suggest that iOS 19's design overhaul could be just as radical, if not more. Apple aims to set a new standard in interface design, possibly integrating elements of visionOS from the Apple Vision Pro into the broader iOS ecosystem.What to Expect at WWDC 2025
With Apple's annual Worldwide Developers Conference (WWDC) set for June 9, expectations are high. The conference is not just a showcase of new software but also a harbinger of Apple's design and technological priorities for the years to come. The first beta of iOS 19 is expected to be released to developers right after the opening keynote, with a public release scheduled for September. Even the WWDC 2025 logo teases potential design elements, adding to the anticipation.
