The iOS 16.4 beta, which Apple made available to developers on Thursday evening, appears to reintroduce the HomeKit architecture update that was removed in iOS 16.2 due to a number of HomeKit bugs.
In the Software Update section of the Home app, iPhone and iPad users who have not yet updated to the new architecture will see update on iOS 16.4 the option "Home Upgrade Available". There have been indications that the HomeKit architecture will be reintroduced in iOS 16.4 as early as January, as Apple has been working on it behind the scenes for some time. Apple has prepared an updated version of the update, presumably with fewer bugs that will affect HomeKit users.
HomeKit architecture update: Apple starts second attempt with iOS 16.4
The new HomeKit architecture is designed to improve the reliability and efficiency of communication between smart home accessories and Apple devices and has been under development by Apple since the announcement of iOS 16 at WWDC in June 2022. When first introduced, some HomeKit devices were missing from HomeKit setups or were stuck in the "Configuring/Updating" status. In addition, HomeKit sharing invitations failed and HomeKit Secure Video recording was not possible for some. (Photo by hadrian / Bigstockphoto)
