Apple to Enforce HomeKit Architecture Upgrade in iOS 18.4
On Monday, Apple rolled out the third developer beta of iOS 18.4. While the update does not introduce any major visual changes, its code reveals a significant shift that will affect HomeKit users.
Apple initially introduced an upgraded HomeKit architecture in iOS 16.2, which was launched in November 2022. This update aimed to improve the performance and reliability of HomeKit accessories. However, due to technical issues reported by users, Apple temporarily withdrew the upgrade in December 2022. The company later reintroduced the improved HomeKit framework in iOS 16.4, released in February 2023.
Mandatory Upgrade for HomeKit Users
Until now, upgrading to the new HomeKit architecture has remained optional. Many users chose to stick with the older version to maintain compatibility with their existing smart home accessories. However, according to findings from 9to5Mac, this flexibility may soon end.
Code from the third developer beta of iOS 18.4 contains warnings instructing users to “update now to avoid interruptions,” as support for the older HomeKit architecture “will end soon.” This suggests that Apple is making the transition to the upgraded HomeKit architecture mandatory, potentially impacting users who rely on older smart home devices.
How the Change Affects HomeKit Users
The forced upgrade means Apple Home app users must transition to the latest HomeKit architecture, regardless of their current setup. As a result:
- Older HomeKit accessories may stop working – Devices incompatible with the new architecture could become obsolete.
- Users must update to iOS 18.4 – Those who want to continue using HomeKit must install the latest iOS update.
- Improved performance and security—The mandatory shift ensures users benefit from the updated HomeKit framework’s enhanced speed, reliability, and security features.
iOS 18.4 Release Timeline and Other Features
Apple is expected to roll out iOS 18.4 to the general public in April. In addition to the HomeKit changes, this update will introduce several new features, including:
- Apple Vision Pro app – Enhancing compatibility with Apple’s mixed-reality headset.
- New emoji characters – Fresher emojis are added for better expression in messaging apps.
- General system improvements – Addressing bugs and optimizing system performance.
While Apple has delayed Siri’s anticipated Apple Intelligence upgrades, iOS 18.4 still brings meaningful updates that enhance the user experience.
What HomeKit Users Should Do Next
To prepare for the mandatory upgrade, HomeKit users should:
- Check device compatibility – Ensure all smart home accessories are compatible with the new HomeKit architecture.
- Back up HomeKit settings – Save configurations to avoid potential setup issues post-upgrade.
- Update iOS when available – Install iOS 18.4 as soon as it rolls out to maintain seamless smart home functionality.
Apple’s decision to enforce the HomeKit upgrade marks a significant step in improving smart home technology. While some users may face challenges with older accessories, the update promises a more secure and efficient smart home experience. Stay ahead by preparing for the transition before iOS 18.4 officially launches.
