Apple’s iOS 28 Codename Leak Points to a 2027 Supercycle

Apple’s next mobile operating system already has a name inside the company, and it is not iOS 28. According to Bloomberg’s Mark Gurman, writing in his Power On newsletter, Apple has quietly begun early development on its 2027 software, with iOS 28 and iPadOS 28 carried internally under the codename Bell, macOS 28 known as “Poppy,” and the combined effort nicknamed “Boppy.” The work is underway a week before the company even shows iOS 27 to the public.

The portmanteau is the fun part. The useful part is what the timing reveals: Apple is now building two operating system generations at once, and it is treating the 2027 cycle as the one that counts.

The Codenames Apple Did Not Announce

Internal codenames are an old Apple habit, and they rarely match the public branding. Gurman reports that engineering teams refer to the 2027 generation as Boppy, splicing Bell and Poppy together the same way the current cycle was stitched into a single label. That current cycle, the software heading to WWDC next week, runs under “Rave” for iOS and iPadOS 27 and “Fizz” for macOS 27, which staff shorten to “Rizz.”

The names sit on top of a public scheme Apple only recently overhauled. At its 2025 developers conference, the company dropped sequential version numbers and switched to year-based branding, jumping from iOS 18 to iOS 26 so the number points to the model year ahead. Under that logic, iOS 27 is the 2026 release and iOS 28 lands in 2027.

Codenames also travel below the OS level. Earlier this year Gurman reported that a chatbot-style Siri being built for the version 27 software carried its own internal tag, “Campos.” The pattern is consistent: Apple assigns playful interim names to features and platforms long before any of it is merged into a shippable build.

Why 2027 Is the Year Apple Is Building Toward

The reason the Boppy generation gets extra attention inside Apple is sitting on the hardware calendar. Gurman has described a multi-year plan to reinvent the iPhone, and the centerpiece is a special 20th anniversary model rumored for September 2027, two decades after the original iPhone went on sale in 2007.

The Anniversary Hardware

Reporting on that 2027 phone points to the most dramatic exterior change in the product’s history. The rumored design leans on a curved display that wraps toward all four edges, an all-glass body, fewer physical buttons, and under-display versions of Face ID and the front camera. Apple is also expected to ship its first foldable iPhone the year before, in 2026, which means the anniversary device would arrive into a lineup that already looks unlike anything the company sells today.

The “Far More Significant” Signal

Gurman wrote that the version 28 releases are shaping up to be far more significant than the version 27 updates, though he did not detail specific features or interface changes. Read against the hardware roadmap, the message lines up. New iPhone form factors need software built to match, from how the interface bends around a curved screen to how the system handles a folding display, and that software work has to start years ahead.

1. 2025: Apple switches to year-based naming, debuting iOS 26 and a redesigned interface.
2. 2026: iOS 27 (Rave) previews at WWDC in June; first foldable iPhone expected later in the year.
3. 2027: iOS 28 (Bell) ships alongside the rumored 20th anniversary iPhone in September.

iOS 27 Is the Refinement Year Before the Overhaul

Before any of the 2027 work reaches users, Apple has a conference to run. WWDC 2026 takes place June 8 to 12 as an online event, with the keynote on Monday, June 8 at 10 a.m. Pacific, per Apple’s official WWDC 2026 developer schedule. That is where iOS 27, iPadOS 27, macOS 27 and the rest of the version 27 lineup get their first public showing.

The pitch for this year leans toward stability and catching up rather than reinvention. Earlier reporting points to a heavy focus on Siri and Apple’s on-device Apple Intelligence features, including a more personal Siri that can read on-screen content, understand user context, and act across apps. A dedicated Siri app for typed and spoken queries and a “Search or Ask” option inside the Dynamic Island have also been reported.

So the version 27 release reads as the bridge. It cleans up the AI promises Apple has been chasing since iOS 18 and steadies the platform, while the heavier design lifting waits for the generation behind it.

Two Development Tracks Running at Once

The detail worth holding onto is that Apple is now visibly working on two parallel tracks. Gurman reports that the Boppy teams are still in the earliest phase, building individual features, new app architectures and design changes that have not yet been merged into complete operating system builds. That is the normal shape of Apple’s calendar, where a release spends well over a year in the pipeline before it previews.

What early-stage development looks like at this point:

• Engineers prototype standalone features and apps in isolation.
• New application frameworks get rebuilt rather than patched.
• Design and interface concepts are tested before any system-wide rollout.
• None of it is stitched into a single shippable OS build yet.

This is the same company that has spent the past year folding artificial intelligence deeper into its platforms, as seen in its AI-driven accessibility tools across VoiceOver and Magnifier. Running a refinement release and a reinvention release side by side is how Apple keeps an annual shipping cadence while still preparing a much larger jump for a milestone year.

What the Leak Leaves Open

Plenty here is still unconfirmed. Apple has not publicly acknowledged the Bell, Poppy or Boppy codenames, nor any feature planned for the 2027 software, and the report stops short of naming what makes that generation bigger. The hardware it is meant to serve is rumored too: respected display analyst Ross Young has cast doubt on whether the anniversary iPhone will actually arrive with a fully bezel-free, all-screen front.

The pieces are also moving fast, and the company’s roadmap has shifted before. A foldable iPhone in 2026 and an anniversary redesign in 2027 are both reported targets rather than dates Apple has set on a stage, and the same goes for the upgrade math driving Apple’s foldable iPhone push up the premium pricing ladder.

For now, the next fixed point on the calendar is June 8, when iOS 27 stops being a codename and becomes a product. The version that staff call Bell gets its own turn on stage at WWDC 2027.

Frequently Asked Questions

What is the codename for iOS 28?

Apple’s internal codename for iOS 28 and iPadOS 28 is reportedly “Bell,” according to Bloomberg’s Mark Gurman. The macOS 28 codename is “Poppy,” and employees use the combined nickname “Boppy” for the overall 2027 software program. Apple has not publicly confirmed these names.

When will iOS 28 be released?

iOS 28 is expected to arrive in 2027, following Apple’s year-based naming scheme where the version number points to the model year ahead. It would typically be previewed at WWDC in June 2027 and released to the public that fall, alongside the rumored 20th anniversary iPhone in September.

What is the iOS 27 codename?

iOS 27 and iPadOS 27 are known internally as “Rave,” while macOS 27 is called “Fizz.” Staff combine the two into “Rizz” when referring to the full 2026 software generation.

When is WWDC 2026 and what will Apple show?

WWDC 2026 runs from June 8 to 12 as an online event, with the keynote on Monday, June 8 at 10 a.m. Pacific. Apple is expected to preview iOS 27, iPadOS 27, macOS 27 and its other operating systems, with a heavy focus on Siri and Apple Intelligence.

Why is iOS 28 considered more important than iOS 27?

Gurman reports the version 28 software is shaping up to be far more significant than version 27, without naming specific features. The likely reason is timing: iOS 28 is expected to be the first version built for the redesigned 20th anniversary iPhone, which calls for deeper changes to the interface and platform.
