iOS 27, currently in beta and set for a fall release, is rumored to include several features not yet present in pre-release versions. Mark Gurman of Bloomberg has a history of accurate leaks, and his reports indicate that some functionalities he detailed may still be added before the final launch or in subsequent updates like iOS 27.1.

These unannounced features include expanded third-party chatbot integration for Siri, allowing users to choose between options like Claude and Gemini alongside ChatGPT. The Health app is also expected to receive AI-powered upgrades, such as improved blood sugar tracking and camera-based workout monitoring, though these may not appear in the initial iOS 27.0 release. Additionally, AI capabilities for image and text generation, currently leveraging ChatGPT, might soon support third-party providers like Claude and Gemini.

Further rumored additions involve a customizable Camera app interface, allowing users to select their preferred controls, and enhanced multitasking features specifically for a potential future iPhone Ultra. While the Camera app has gained a Siri mode, full customization is not yet evident. The anticipation for a foldable iPhone is also suggested by the widespread support for landscape mode in iOS 27, with side-by-side app multitasking expected upon its arrival.
