Developers discovered code in the iOS 27 beta referencing fold states and hinge angles, suggesting Apple is developing a foldable iPhone [1].
The discovery is significant because it provides the first technical evidence that Apple is preparing its operating system for hardware capable of folding. While the company has not officially announced a foldable device, the presence of these specific APIs indicates a strategic move into a market currently dominated by competitors.
The code was found within the iOS 27 [1] beta distributed to developers this month in June 2026 [2]. The codebase reportedly contains support for multiple built-in displays and specific references to hinge angles [1]. These findings have led some analysts to refer to the potential device as the iPhone Ultra Fold [1].
Technical details in the beta include fold-related APIs that would allow the software to recognize when a device is partially or fully closed [1]. This functionality is essential for adjusting user interfaces across a flexible screen, a requirement for any foldable smartphone.
The beta was released ahead of the Worldwide Developers Conference (WWDC) 2026 [2]. Apple has not issued a statement regarding the leaked code or the existence of a foldable handset.
Despite the technical clues, the company has a history of including experimental code in beta releases that does not always result in a commercial product. However, the specificity of the hinge and fold state markers suggests a more advanced stage of development than previous rumors had indicated [1].

This leak suggests Apple is moving beyond the research phase of foldable technology and into software integration. By embedding fold-state logic into iOS 27, Apple is establishing the foundational framework necessary to launch a foldable device that can compete with existing foldable handsets in terms of software fluidity and multitasking.
