Preparing your iPhone for Siri AI

iOS 27 includes a rebuilt search architecture for Siri AI. As a result, iPhones running the iOS 27 beta go through a re-indexing process that can take many days to be completed, but iOS 26. 6 should help to speed things up for users who skip the beta. iOS 26. 6 "optimizes the Spotlight index to prepare for iOS 27," according to Apple's release notes for the update, which will likely be released next week.
