The Nielsen Norman Group doesn't like iOS 26, the new iPhone operating system with Liquid Glass, and why should they? The user interface makes many, many elementary mistakes. Few if any would have been made had the designers read Donald Norman's seminal book on usability—yes, the same Norman from the Nielsen Norman Group—The Design of Everyday Things. Like Windows 8 and sadly many elements of iOS before this, iOS 26 applies the book's principles in reverse. User confusion and frustration is therefore no surprise. The real question is, what in the world happened to Apple's organization to allow this, when it previously blazed a trail for usable technology and made The Design of Everyday Things required reading?
