Apple engineers voice concerns over Siri updates in iOS 26.4.

Apple’s upcoming iOS 26.4 promises a major overhaul of Siri, powered by Apple Intelligence, but internal reports suggest not all staff are fully satisfied with the new system’s performance.

This was reported by MacRumors.

Internal Apple staff question performance of redesigned Siri in iOS 26.4.

According to Bloomberg’s Mark Gurman, some Apple software engineers have expressed "concerns" about Siri’s revamped functionality, though the specifics of these issues remain undisclosed.

The update, expected in March or April 2026, still gives Apple several months to address any lingering problems before the official rollout.

Apple first introduced the redesigned Siri at WWDC 2024, highlighting features such as on-screen awareness, personal context, and deeper in-app control. Demonstrations included Siri answering questions about a family member’s flight and lunch plans using information pulled from Mail and Messages.

Initially slated to launch with iOS 18.4, the upgraded assistant was delayed. In July, CEO Tim Cook assured users that development was progressing well and that the new capabilities were on track for release next year. Yet, if challenges persist, even the iOS 26.4 timeline could be impacted.
