Release notes

Overview

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

iOS 18.1 delivered the first public Apple Intelligence feature set on supported iPhones. Writing Tools, a revised Siri experience, notification summaries, Reduce Interruptions, and new Photos search and cleanup tools brought assistance into communication, focus, and media workflows.[1]

The release also added call recording and transcription, expanded Camera Control, and enabled AirPods Pro 2 hearing features in supported regions. Apple Intelligence and health capabilities have device, language, and geographic requirements, so their inclusion does not imply universal availability.[2][3]
