Apple Kicks Off iOS 28 and macOS 28 Development with ‘Bell’ and ‘Poppy’ Codenames

The Long Game in Cupertino
Apple typically operates with a level of secrecy that borders on the monastic, but the company’s software pipeline is rarely a secret for long. While the tech world is currently bracing for the imminent unveiling of iOS 27 at the Worldwide Developers Conference (WWDC 2026) next week, internal movement suggests Apple is already looking significantly further down the road.
According to the latest Power On newsletter from Bloomberg’s Mark Gurman, Apple has officially pivoted a portion of its engineering resources toward the 2027 software cycle. The company has reportedly begun early development on what will eventually become iOS 28, iPadOS 28, and macOS 28. This overlap in development cycles is common for Apple, but the specific internal identifiers for this era have finally surfaced.
‘Bell’ and ‘Poppy’: Breaking Down the Codenames
Inside Apple, the 2027 mobile operating systems—iOS 28 and iPadOS 28—are currently being developed under the codename “Bell.” Meanwhile, the desktop experience for the Mac, macOS 28, is referred to as “Poppy.”
In a quirk of corporate culture typical of Apple’s engineering teams, employees have reportedly begun blending these two identifiers, referring to the collective software initiative as “Boppy.” This linguistic shorthand often signals a tighter integration between the mobile and desktop ecosystems, reflecting a broader trend of Apple blurring the lines between how its chips and operating systems interact across different form factors.
Fragmented Development and the ‘Feature-First’ Approach
It is important to note that “development” at this stage does not mean a cohesive operating system is already running on test devices. Gurman notes that Apple’s engineering teams are currently operating in a fragmented state, focusing on the construction of individual features, standalone applications, and core platform improvements.
These elements have not yet been merged into a unified OS build. In the Apple workflow, this phase is critical for experimentation. By building features in isolation, teams can pivot or scrap concepts without destabilizing a primary build. This suggests that while the 2027 cycle has begun, the final feature set for iOS 28 remains fluid.
Why the Early Start Matters
The decision to accelerate the 2027 timeline suggests that Apple may be planning more substantial architectural shifts than what we expect to see in the upcoming iOS 27. While the next immediate release is expected to refine Apple Intelligence and potentially overhaul Siri’s deep-link capabilities, the “Bell” and “Poppy” era could be where Apple implements more fundamental changes to the kernel or user interface.
Historically, Apple uses these early windows to align software capabilities with new hardware silhouettes. With the ongoing evolution of the M-series silicon and the potential for new wearable categories, starting the software groundwork now ensures that the 2027 hardware will have an OS that isn’t just “catching up” to the silicon’s capabilities.
For now, the industry’s immediate focus remains on the WWDC 2026 stage. However, the existence of “Boppy” proves that even as Apple prepares to ship the present, it is already meticulously sketching the blueprint for the future.
