The entire week of WWDC has taken place in Cupertino, and we’ve had some good news, both pleasant and not so pleasant, regarding the future of Apple’s operating systems and some hints about possible products. According to a session related to flexible UIKit apps, a comment from Apple drew attention regarding screen formats. This could give us a new clue about the Cupertino company’s foldable iPhone.
iOS 26 and a new hint about the foldable iPhone at WWDC 2025
Apple indicated that in iOS 26 and its SDK, apps will no longer “scale to new screen sizes” to support future hardware. They will also no longer automatically resize to letterbox. Previously, when Apple made changes to screen sizes due to a taller iPhone or a new aspect ratio or display on the iPad, any app created using an older SDK would automatically scale. In this case, developers will need to update their app with the iOS 26 SDK and submit it to the App Store.
It’s very strange that Apple would directly refer to new hardware, although this could be very natural or odd from the perspective of how you look at it. What product could possibly have new hardware and a new screen size? iPhones, iPads, and Macs won’t grow any larger unless they make a foldable size, which would be a game-changer for both Apple and developers.
The aspect ratio will be important on the foldable iPhone
On Weibo, leaker Digital Chat Station has exposed information regarding the iPhone’s folding engineering prototype. In this case, there was a slight change in the screen size. Surprisingly, the aspect ratio remained unchanged. The inner screen will have a 14.1:10 ratio and the outer screen a 14.6:10 ratio. The current aspect ratio of iPhones is 19.5:9, while older generations retain a 16:9 ratio, according to 9to5Mac .In the case of the folding iPhone, it would be a smaller aspect ratio, which is why Apple is preparing to reduce negative effects that could affect the display of apps and content.
It’s very important that Apple is making the changes that have been outlined, regardless of whether it refers to the arrival of the foldable iPhone. Apple can’t afford to have any problems when the foldable iPhone is ready to launch. It’s a good way to eliminate risks regarding future user interfaces, and if Apple intends to have more foldable devices, this is the way to go.
