Macworld reports that the new AI-powered Siri in the iOS 27 developer beta handled detailed, real-world tests with notably improved accuracy. In a hands-on trial, Macworld found Siri answered specific Taylor Swift questions, identified songs from The Eras Tour, and executed complex Apple Music requests using natural language. The review notes the assistant is more context-aware, with access to emails, calendar events, files, and messages, per the beta build. Macworld tested the beta on iPhone 15 Pro and M1 Macs/iPads, and describes the feature set as built on a new AI foundation. This was reported in Macworld’s June 12, 2026 feature; Apple has not been quoted in the article on rationale or broader rollout details.
