iOS 27 Beta Hints at Apple's Foldable Device
The iOS 27 developer beta includes framework references like "foldState" and "angleDegrees" for foldable devices, signaling that Apple's first foldable iPhone, expected this year, is progressing.
According to Engadget, Apple included multiple framework references indicating the existence of its first foldable device in the initial developer beta of iOS 27, released on June 8, 2026. The discovery was made by developer Sam Henri Gold, and 9to5Mac has verified the content.
Discovered Framework References
What Gold found inside the iOS 27 framework are terms such as “foldState” and “angleDegrees.” These are likely used to manage the display state (open/closed) and hinge angle of a foldable device. Additionally, language indicating the total number of built-in displays on a host device was included, suggesting that the OS anticipates a form factor with multiple displays, rather than a traditional single-screen smartphone.
Significantly, these references were not present in iOS 26. 9to5Mac has confirmed they are new additions in iOS 27, which is seen as evidence that Apple is intensifying OS preparations for a foldable device.
Mention at the Developer State of the Union
Furthermore, at the developer event “State of the Union” held the same day, Apple announced support for macOS mirroring and resizing iPhone apps on the iPad. At first glance, these appear to be convenient additions for iPad and Mac users, but from the editorial team’s perspective, this is likely a precursor to introducing a new form factor—the foldable device. For foldables, where screen size differs between open and closed states, a mechanism for apps to resize flexibly is essential.
Rumored iPhone Fold Launch This Fall
At this point, Apple has not made any official announcement about a foldable device, but industry observers widely believe that the first foldable iPhone (tentatively called iPhone Fold) will be announced in the fall of 2026. The experimental release of the iPhone Air last year is also seen as a stepping stone. If a product is announced in the fall, it is almost certain to run iOS 27, which was released as a beta today.
From Apple’s perspective, given the many foldable devices already on the market and the nature of developer betas exposing internal OS details, it is difficult to completely conceal preparations for a new form factor. Apart from what Apple officially announced during the WWDC keynote, part of its strategy can be inferred from the beta version.
Editorial Opinion
The biggest focus over the next three to six months will be whether Apple officially announces a foldable device. The framework references discovered today indicate that the software foundation is already nearing completion. While foldable devices from the Android camp have undergone several years of evolution, the differentiating factors in Apple’s late entry will be closely watched. Notably, iOS 27 also brings a Siri AI overhaul, and the combination of foldable-specific multitasking experiences with AI could be key.
Over a longer one-to-three-year timeframe, Apple’s entry into foldable devices is expected to accelerate a form-factor restructuring across the entire smartphone market. Existing players like Samsung, Google, and Oppo will face new competitive pressure in terms of pricing and durability. For app developers, this could standardize UI design tailored to foldable screens, driving overall ecosystem evolution.
A question from the editorial team: details about the hinge mechanism and display technology Apple will adopt for its foldable remain unknown. To what extent can Apple leverage its supply chain strength to overcome issues like creasing and durability that have plagued competitors? Additionally, the price range of the iPhone Fold will be a critical variable affecting its adoption speed.

Frequently Asked Questions
- When will the iPhone Fold be announced?
- Industry speculation points to a fall 2026 announcement. Since the iOS 27 beta includes framework references for foldable devices, a release within this year is highly likely.
- What specific foldable device support does iOS 27 have?
- "foldState" likely indicates the display's open/closed state, and "angleDegrees" the hinge angle. This will allow apps to dynamically change their layout based on the screen's state.
- Can the current iPhone use foldable UI features?
- The framework added in the iOS 27 beta is intended for foldable devices only; these APIs are not expected to function on current iPhones. Apple is likely to officially support them alongside the new device.
