iOS 28 for iPhone 20, MacOS 28 for MacBook Ultra codenames revealed; big redesign tipped

With the official release of iOS 27 and macOS 27 still on the horizon, Apple has already started the development on its major 2028 operating system updates, says a top tipster.

According to the leaked info, the company is treating these upcoming versions as a significant evolution, as they are being designed to support the hardware slated for the rumored 20th anniversary of the iPhone.

The development process is currently in its early stages, with teams focused on individual features, new application architectures, and design enhancements. While the company has not yet integrated these elements into the final versions of the operating systems, the project is already gaining momentum:

• iOS 28 and iPadOS 28, are reportedly codenamed "Bell"
• macOS 28 is known internally as "Poppy", says the leak

Apple employees refer to this entire slate of 2028 software updates as "Boppy", which suggests the integration between the two might be the main focus.

By comparison, the current development cycle, made of iOS 27, iPadOS 27, and macOS 27, is referred to internally as "Rizz," following the "Rave" and "Fizz" internal codenames assigned to the mobile and desktop platforms, respectively.
