It seems like iOS 18 is poised to introduce some intriguing new features related to Safari browsing and visual search. Here’s a breakdown of the information available:

1. Safari Browsing Assistant: Backend code suggests the inclusion of a browsing assistant within Safari. This assistant could utilize iCloud Private Relay’s infrastructure to transmit data to Apple in a privacy-focused manner. It’s unclear whether this feature will require an iCloud+ subscription.
2. Generative AI Features: iOS 18 is rumored to integrate generative AI features, and the Safari browsing assistant could be part of this enhancement. Several iPhone web browsers already leverage AI tools for tasks like summarizing web pages.
3. Encrypted Visual Search: The backend code also references an “Encrypted Visual Search” feature. While details are scarce, this could relate to advancements in visual search capabilities, possibly enhancing existing features like Visual Look Up that identify objects in photos and videos.
4. Debut at WWDC 2024: Apple is expected to unveil iOS 18 during its WWDC keynote on June 10, 2024. This event will likely provide more insights into these potential new features and their functionalities.

As more information becomes available closer to the iOS 18 release, we can anticipate a clearer picture of how these enhancements will impact Safari and visual search experiences on iPhone devices.
