All the foldable iPhone Ultra hints in the iOS 27 beta

Apple unveiled a ton of new features and updates during this week's WWDC keynote. From the brand new Siri AI to Spatial Reframing, the internet is still talking about what's coming in the latest Apple operating systems like iOS 27 and macOS 27 Golden Gate.

However, the biggest announcement may be what Apple didn't mention during the keynote. And while we didn't get any direct mentions of the iPhone Fold Ultra, the company seems to have shared the news unintentionally in its new iOS 27 developer beta.

Code found within the new iOS 27 beta appears to confirm the long-awaited foldable iPhone.

The foldable iPhone, which has been called iPhone Fold but may end up officially going by the name iPhone Ultra, seems to be referenced in iOS 27 code, according to developer Sam Henri Gold.

iOS 27's framework has new parameters that mention “foldState” and “angleDegrees.” These references were not in previous versions of iOS, and seem like pretty straightforward references to a foldable device.

"foldState" directly references a foldable device and “angleDegrees" can refer to the angle at which the foldable iPhone is opened at.

Gold posted his findings on the social media platform X. The developer also found that the new iOS 27 beta checks the device to get the total number of built-in displays. 

Every single iPhone that has ever been released up to this point has a grand total of one built-in display. If Apple is adding this to the latest iOS, that's yet another sign pointing to a new foldable device with more than one display. Based on early leaks and dummy units, the foldable iPhone will feature a large foldable display as well as an outer display that can be used when the device is closed.

After the iOS 27 developer beta went live, it didn't take long for the tech world to find other indirect references to the foldable. Journalist Mark Gurman and tech creator Marques Brownlee both shared these hints with their followers on social media, with Gurman noting, "LOL could they be any more blatant?"

Rumors and reports have strongly pointed to a September announcement and end-of-year release date for Apple's foldable iPhone. However, Apple has not yet officially announced the device. These findings within the code of the iOS 27 beta are the strongest direct indication yet that it exists and that Apple is indeed planning to drop a foldable iPhone sometime in the very near future.
