Background of Foldable Technology and Apple’s Preparations
While foldable phones have been available from Android manufacturers for several years, Apple has historically been cautious in adopting this form factor. Recent developer discoveries, including new API terms like foldState and angleDegrees, indicated Apple’s internal work on foldable support. The company’s emphasis on designing for a dynamic range of sizes aligns with the upcoming hardware, which has been rumored for months, including reports of a book-style foldable iPhone with a 7.7-inch inner display and a cover screen. The device is expected to be announced alongside the iPhone 18 Pro in September, with mass production slated for July.
