Apple released the first developer betas of iOS 27.3 and watchOS 27.3 this week, expanding Siri AI with deeper app actions and bringing select Apple Intelligence features to China under an Alibaba content filter. On Apple Watch Series 12 and Ultra 4 the betas add Audio Intelligence tools including Siri Recap conversation summaries and Live Rewind for the prior 15 seconds. A redesigned Health app with new Insights and Longevity sections is also in testing. Public betas followed quickly, with a full December rollout expected.
