Apple revealed clues to the possible launch of its foldable iPhone during WWDC 2026. Software researcher M1Astra uncovered terms like 'foldState', 'mechanicalAngleDegrees' and 'angleDegrees', which describe a folding device's behaviour, in iOS 27 code strings. Apple is also allowing expansion of certain widgets into a full-screen format, which could make more sense on a foldable device.
