Code sleuths are diving into iOS 27 and finding hints about the unreleased iPhone Fold, and finding subroutines that report just how open or shut the foldable might be.

Apple does its best to hide any code that might give away some future product, but it isn't always perfect. Code references in iOS 27 show some of what Apple is preparing for the upcoming iPhone Fold.

Even though there hasn't been a single component leak or information about mass production starting, some believe iPhone Fold is still coming in September. These bits of code certainly suggest Apple is working to release iPhone Fold, but say little else.

The code shared by the social media user shows items for "foldState," "angleDegrees," and a reference to the number of present hardware displays. These are all clear references to the existence of an iPhone Fold.

Of course, there have been rumors, patents, and various dummy units confirming an iPhone Fold has been in the works since at least 2019. This is the first instance of iOS directly referencing the future foldable, which means it could be imminent.

However, Apple has feature flags meant for operating systems that are years away, so the discovered code could also provide nothing in terms of the release timeline. Time will tell if the product will actually be ready for its expected September debut.
