iOS 19 is anticipated to be announced in June 2025, featuring a "more conversational Siri" enhanced by advanced language models, akin to ChatGPT. However, some features, including the revamped Siri, may be delayed until spring 2026. The update will be compatible with iPhones running iOS 18, including the iPhone XS and XR. The first betas are expected at WWDC 2025, with a full release likely in September.
