Apple iOS 27 Beta 2 Firmware Reveals 'Baidu Visual Search' Component

There’s more hiding inside iOS 27 Beta 2 than the headline features suggest. A firmware analysis by One Jailbreak, published June 23, turned up a new component called “SearchPartnerInferenceProvider” tucked inside ExtensionsKit — and its localization strings explicitly name “Baidu Visual Search.”

The researchers compared two firmware builds — 24A5355q (Beta 1) and 24A5370h (Beta 2) — and found a surge of new Frameworks, Daemons, Feature Flags, and localization strings that reveal where Apple’s engineering attention is concentrated.

The ExtensionsKit addition is the most revealing find. The media outlet believes this component is infrastructure Apple is building for third-party visual search and AI service providers. Rather than handling everything in-house, Apple might offer different search partners depending on the region. Right now, Baidu is the only named partner in the firmware — which makes this change particularly significant for the Chinese market.

iOS 27 Beta 2 also introduces a new SystemVoiceAssistant app, along with expanded eligibility checks, regional restrictions, recovery state handling, and download management tools. These additions suggest Apple is building a more flexible smart assistant framework — one that could eventually let users bind different AI assistants or third-party apps to the iPhone’s side button.

On the audio side, Apple pulled the Polaris audio framework out of its private Framework and turned it into a standalone daemon called “polarisd” with elevated permissions. A new bluetoothaudiod process now handles Bluetooth audio separately.

Behind the scenes, Beta 2 ships with over 4,200 updated dylibs, 732 updated Mach-O executables, and nearly 300 Kernel Extension updates. That’s a lot of optimization work that doesn’t make the release notes but keeps the OS running smoothly.
