Yesterday Apple held the opening keynote of the WWDC 2026. The great protagonist was Siri AIthe long-awaited update that comes from Google’s AI, but they announced more news and there was one in particular that Apple did not mention, but which is the clearest clue of a highly anticipated device: the foldable iPhone.
The function we are talking about is the ability to resize windows in iPhone Mirroring mode. Apple didn’t show it at the presentation, but rather it was discovered by developer Dylan McDonald, who showed it in action in X. You can also see in this post in X from a Macrumors analyst.
How it works and why it is important
iPhone Mirroring is a feature that allows us to view the iPhone screen directly on the Mac, as if it were a floating window. This window has the format of the iPhone screen, but in the betas of iOS 27 and MacOS 27, these developers have seen that the window can be resized, adopting a format like that of the iPad.
Until now, if you mirrored the screen on the Mac, the format of this window was fixed. The fact that it allows it to be enlarged is one of the strongest evidence we have of the existence of a foldable iPhone, which you can change your screen format depending on whether we use the exterior screen or the interior screen. Of course, at the moment it can only be done with apps that have adopted iOS 27
By the way, iPhone mirroring is not available in the European Union, although There are ways to activate it.
What do we know about the foldable iPhone
Although Apple has not mentioned it directly and it is not yet official, the rumors are increasingly intense. Everything indicates that the iPhone Fold (as it is believed to be called) will have a book type design like that of the Galaxy Z Fold, with a 5.5-inch exterior screen and a 7.8-inch interior screen.
The characteristics that have been leaked pose a aluminum design with titanium reinforced parts120Hz OLED screens and four cameras, two on the back and one on each screen. As for hardware, it is expected to feature a next-generation chip (probably an Apple A20 Pro), 12GB of RAM, and up to 1TB of storage.
What there are more doubts about is the release date. Most information indicates that will be announced in September of this year, but its arrival on the market would be later. We recently talked about how Apple had encountered unexpected problems in the engineering phase which could make it take longer than expected. In September we will clear up doubts, but the fact that they are already including this type of functions in the next version is an argument in favor of a presentation this year.
