The iOS 16.4 beta provided by Apple for developers today appears to reintroduce the HomeKit architecture update that was removed from iOS 16.2 due to numerous bugs. If iPhone and iPad users have not yet upgraded to the new architecture, they will see the option "Home Upgrade Available" in the Software Update section of the Home app after updating to iOS 16.4. Apple has been working on reintroducing the HomeKit architecture since January and has prepared an updated version with fewer bugs. This new architecture aims to enhance the reliability and efficiency of communication between smart home accessories and Apple devices. It has been in development since the announcement of iOS 16 at WWDC in June 2022. The initial launch of the new architecture resulted in issues such as missing devices, stuck configurations, failed invitations, and broken secure video recording. In other news, Apple is expected to unveil the iPhone 15 lineup in September, with rumors suggesting several new features for the Pro and Pro Max models. Apple has also released the second public betas of iOS 17 and iPadOS 17 for public beta testers. Additionally, there have been ongoing rumors about the repairability of the upcoming iPhone 15 Pro and iPhone 15 Pro Max models, with suggestions that their redesigned chassis will make them easier to repair, possibly featuring a removable rear window.
