Code in iOS 27 seems to prove iPhone Ultra will use Touch ID

It's been widely predicted that the iPhone Ultra 's chassis will be too thin for Face ID, but now code references in the iOS 27 beta back up the presumption that Touch ID will be used instead. iPhone Ultra render Face ID was introduced with the iPhone X in 2017 and Apple has been steadily adding it to devices ever since. There has been one notable exception with the iPad Air sticking to Touch ID , and now it appears confirmed that the iPhone Ultra will be the same.
