The index-based list navigation method, prevalent in iOS applications, allows users to quickly jump to specific sections within a long list by selecting a letter or symbol from a vertical alphabet displayed alongside the list. For example, in the Contacts app, a user can tap the letter ‘S’ to immediately navigate to contacts whose names begin with that letter.
This feature enhances user experience by providing a fast and efficient alternative to scrolling through extensive lists. Its incorporation into the iOS design language reflects a focus on usability and accessibility, particularly when dealing with large datasets. The design has been a consistent element in iOS applications for many years, demonstrating its continued relevance and effectiveness.
