There weren’t a large number of improvements to Vision in iOS 26, but there is a new API that extends on the API seen in the last demo. The RecognizeDocumentsRequest API improves on the functionality seen in RecognizeTextRequest by providing the ability to read structural elements of a page, like tables, lists, and important information like phone numbers. It also provides support in 26 languages. The new API can also provide an estimate of camera lens smudge detection, which is actually used in the Camera app in iOS 26. Let’s take a look at the new structure detection in a demo.
