The release of iOS 18.1 beta 7 marks a significant milestone for Apple, introducing a suite of advanced features under the umbrella of Apple Intelligence.

Every person has a unique heartbeat, so it would be possible to use this as a means to unlock the iPhone. At the moment this could only be achieved through the Apple Watch, but that could change.

Apple Intelligence, a suite of AI-powered features for iPhones, comes with enhanced tools for Photos, Mail, and Siri. It is being rolled out with iOS 18.1.
