WWDC 2026 was all about software, with new versions of iOS, iPadOS, macOS, and more unveiled. But while hardware didn’t take center stage, it was present in the background, with Apple hinting at (and in some cases all-but-confirming) its long-rumored foldable phone, believed to be called the iPhone Ultra.
These clues came in announcements, software changes, and even buried deep in code, and combined, they strongly point to the iPhone Ultra not just being in the works, but probably launching soon.
So, below, we’ve detailed the various WWDC clues that hint at the iPhone Ultra’s existence.
Watch On
1. Mentions of a foldable phone in iOS 27 beta code

Perhaps the most telling sign of the iPhone Ultra’s existence can be found within iOS 27 itself, as code within the first beta found by Sam Henri Gold contains mentions of “foldState” and “angleDegrees.”
Both of these references seem like they’d only be relevant to foldable devices, and since the mentions are in an iOS beta, they evidently concern an iPhone, specifically.
This code also isn’t present in iOS 26, so it’s been newly added, suggesting that checking for fold states will be relevant before the launch of iOS 28. That in turn means we’ll probably see the iPhone Ultra before too long — with most leaks pointing to September.
2. A check for how many screens a device has

The same source has also found a check in the iOS 27 developer beta for how many built-in displays a device has.
Since this is iPhone software and no iPhone currently has more than one screen, this is another obvious hint that a multi-screen device — such as a foldable phone — is on the way.
3. Resizable iPhone Mirroring

At WWDC 2026, Apple debuted the ability to resize the iPhone Mirroring window on Mac, allowing you to make it bigger and more like an iPad display — or more like a large foldable screen.
Now, this could just be about making your iPhone’s display appear bigger and more readable on a large desktop screen, but displaying it in a larger size would also be necessary for the iPhone Ultra, which will probably be able to switch between a phone-sized cover screen and a near tablet-sized foldable display. As such, this feature feels like it’s laying the groundwork for Apple’s foldable phone.
4. Resizable apps and developer encouragement
As well as being able to resize your iPhone screen when mirroring it on a Mac, Apple is also making it easier for developers to resize apps to support a variety of display sizes, which similarly seems to hint that new screen sizes are coming.
And the company is making a real push for developers to embrace this change, encouraging them during WWDC’s Platforms State of the Union to allow their apps to support “a dynamic range of sizes and aspect ratios,” rather than designing apps to work just for specific devices or screen sizes.
5. Larger widgets

Finally, iOS 27 is adding larger 4×6 widgets, which can fill up an entire iPhone home screen. While some people will probably find this useful on existing iPhones, these widgets are likely to be more beneficial on the iPhone Ultra, where a widget that size would probably fill just around half of the foldable screen.
So, while not as obvious a hint as some of the above ones, this too feels like a feature that’s been designed with larger — and perhaps foldable — iPhone screens in mind.
