Overview

Editorial synthesis with inline references and a source ledger when citations are available.

iOS 18.3 extended Visual Intelligence on iPhone 16 models with calendar-event extraction and plant or animal identification. It also made notification summaries easier to manage and visually distinguish, while temporarily disabling summaries for News and Entertainment apps.[1]

Smaller corrections covered repeated Calculator operations, the keyboard during typed Siri requests, and Apple Music audio that could continue after the app was closed. The release also carried a separate set of documented security fixes.[2][3]
