iOS 26.5 ships end-to-end encryption for RCS messaging, currently in beta. This is the first time Apple has brought E2EE to cross-platform SMS successor messaging, closing a long-standing security gap between iPhone and Android users. The update also patches documented iOS vulnerabilities and surfaces AI prompt strings inside the private CoreUtils framework, a detail that signals active Apple Intelligence infrastructure work happening below the public API layer.
The update is dense with smaller but consequential changes: ads are coming to Apple Maps, new in-app subscription models are available for App Store developers, FaceTime calls from unknown numbers can now be silenced at the notification level, and a new Apple Intelligence extension gains access to health data. The EU build adds Notification and Live Activity Forwarding plus expanded third-party audio hardware support via AudioAccessoryKit. iPad gets automatic Magic device pairing.
The reason to watch the full video is not the headline RCS feature. It is the breakdown of the AI prompt strings in CoreUtils, the new TCC reminderPrompt feature flag, and the health data extension, three undocumented additions that point directly at what Apple is building toward WWDC 2026. Jeff Benjamin of 9to5Mac runs through all 13 chapter segments with timestamps, making it easy to skip to the technical details that matter most to you.
