The recent release of the iOS 27 beta has provided compelling evidence that Apple is working on a foldable phone, commonly referred to as the iPhone Fold. Observations by developer Sam Henri Gold noted specific terms in the iOS 27 framework documentation, such as 'foldState' and 'angleDegrees', which indicate that the operating system is designed for devices with multiple displays. This feature was absent in the previous iOS 26, further supporting the notion of a new device form factor. Additionally, during Apple's developer State of the Union, the company announced enhancements for resizing iPhone apps, which could be a precursor to the introduction of the foldable phone. With the anticipated launch of the iPhone Fold expected this fall, the integration of these new features into iOS 27 aligns with Apple's push towards innovative device designs. As the market for foldable phones continues to grow, Apple's preparations suggest they are ready to enter this segment, making it increasingly difficult to maintain secrecy around their developments.
