Apple has delayed a significant number of iOS 19 features, according to Bloomberg's Mark Gurman. These features, originally slated for iOS 19, are now expected in the iOS 19.4 update in spring 2026.
This delay isn't unprecedented, mirroring the rollout of Apple Intelligence in iOS 18, where the revamped Siri was also postponed to a later update. Siri's "New Era": A Phased Approach with Challenges discusses similar delays and challenges faced by Apple.
While the specific delayed features remain undisclosed, Gurman confirms they extend beyond the new LLM Siri. This enhanced Siri, designed to function similarly to ChatGPT and Google Gemini, is anticipated a few months before iOS 20's unveiling. Apple's Conversational AI Chatbot "LLM Siri" Coming in 2025 provides further details on this development.
iOS 19 is expected to debut at WWDC in early June 2025, with a public release in September alongside the iPhone 17, potentially including the new iPhone 17 Air. iOS 18.2: Mail App Gets Major Redesign offers insights into recent iOS updates and potential future design directions.
