iOS 19 Delay: Siri Overhaul and More Pushed to Spring 2026

iOS 19 Delay
Apple delays key iOS 19 features, including the "LLM Siri" upgrade with large language models (LLMs), to Spring 2026. The updated Siri is now expected in iOS 19.4, following the initial iOS 19 release in September 2025 alongside the iPhone 17.

Apple is reportedly delaying a significant number of features originally planned for iOS 19, including a major Siri upgrade. These features are now expected to be included in iOS 19.4, slated for Spring 2026.

Siri Overhaul: The ‘LLM Siri’ Initiative

One of the key features expected in iOS 19 is a major upgrade to Siri, internally referred to as “LLM Siri”. This revamped assistant will integrate advanced large language models (LLMs) to handle tasks more intuitively, similar to platforms like ChatGPT and Google’s Gemini.

Announced alongside iOS 19 at WWDC 2025, this upgraded Siri will not debut until iOS 19.4. The updated Siri is expected to perform complex tasks, summarize text, and interact with third-party apps through improved App Intents. Apple aims to incorporate features prioritizing user privacy, setting its AI capabilities apart from competitors.

iOS 19 Timeline and iPhone 17 Release

iOS 19 is set to be unveiled at Apple’s annual WWDC event in June 2025, with its first public release slated for September 2025, coinciding with the launch of the iPhone 17 lineup. The new devices are rumored to introduce a completely new form factor, tentatively called the “iPhone 17 Air”.

Current Progress and Future Upgrades

Siri’s transformation is part of Apple’s gradual AI strategy, starting with minor improvements in iOS 18. Recent updates introduced features like a redesigned interface, better handling of commands, and the ability to type requests. December’s iOS 18.2 update will further integrate ChatGPT, while iOS 18.3 will enable Siri to understand personal contexts and perform app actions.

However, the current updates are only incremental. Apple appears to be adopting a staggered approach to releasing features. While iOS 18.4, arriving this spring, will include significant updates, many capabilities originally planned for iOS 19 are now postponed. This method allows Apple to refine its technology before release but also highlights the challenges of building in-house AI solutions.

Despite delays, Apple is working actively on in-house solutions to enhance Siri’s conversational capabilities and eliminate reliance on third-party AI providers in the long run.
