Apple didn’t say a word about a foldable iPhone at WWDC 2026. It didn’t have to.
While Apple’s WWDC 2026 keynote focused on software updates, developers digging through the first iOS 27 beta have uncovered several references that appear to point directly to foldable hardware.
According to findings highlighted by developer Sam Henri Gold and researcher M1Astra, new framework strings in iOS 27 include references such as “foldState,” “angleDegrees,” and “mechanicalAngleDegrees.” The code also includes a function designed to identify the number of built-in displays connected to a device.
Taken together, the discoveries suggest Apple is building software capable of detecting whether a device is folded, how far it has been opened, and whether it is operating with more than one integrated display.
The references were not present in earlier versions of iOS, adding weight to speculation that Apple is preparing its software platform for a new category of hardware.
Apple pushes developers toward flexible app design
The software clues arrived alongside a broader message from Apple aimed at developers during this year’s Platforms State of the Union presentation.
Apple encouraged developers to move beyond designing apps for fixed screen sizes and orientations. Instead, the company said developers should build experiences that can adapt to changing display dimensions.
During the session, Apple said developers should design for “a dynamic range of sizes and aspect ratios,” MacRumors reported. The company also introduced support for resizable iOS applications, new testing tools in Xcode, and simulator features that allow developers to preview apps across different screen sizes.
Apps built with the latest SDK will automatically gain support for resizable layouts, while developers using SwiftUI are already, in Apple’s words, “well on your way to supporting full resizability.”
The changes were presented as improvements for iPhone Mirroring and iPad experiences, but observers note that the same capabilities would be essential for a foldable device that shifts between phone-sized and tablet-sized displays.
Several newly announced iOS 27 features appear to fit naturally with a larger, flexible display. Reports indicate that widgets can now expand to full-screen views in apps such as Music, News, and Weather. Apple has also expanded iPhone Mirroring support in macOS 27 to accommodate larger layouts.
Analysts argue that these changes make more sense in a future where an iPhone can unfold into a significantly larger screen.
September launch rumors grow stronger
Apple has not officially announced a foldable iPhone, but reports across the industry continue to point toward a September unveiling alongside the iPhone 18 Pro lineup.
The device is widely expected to adopt a book-style folding design, with rumors suggesting a larger inner display and a smaller outer screen. Reports have also pointed to premium materials, a redesigned hinge system, and a price tag that could exceed $2,000.
The code discoveries do not confirm that a foldable iPhone will launch this year. However, they represent some of the clearest evidence yet that Apple is actively preparing iOS for hardware that bends, unfolds, and potentially operates across multiple displays.
Meanwhile, Apple Watch owners may want to check their wrists: watchOS 27 is dropping support for several popular models, including the original Ultra, Series 6 through 8, and the second-generation SE.
