During the WWDC25 conference, Apple announced a postponement of the integration update for Siri, now set to arrive in 2026. Craig Federighi, Apple's Senior Vice President of Software Engineering, elaborated that the initial V1 architecture fell short of quality benchmarks, necessitating a shift to a more sophisticated V2 end-to-end architecture to fully realize Siri's capabilities. Moving forward, Apple will persist in enhancing Siri's features, with the highly anticipated personalized Siri scheduled for release alongside iOS 26.4 in spring 2026.
