Last week, Apple released the first build of the upcoming HomePod’s firmware, allowing curious developers to unpack the code and learn a few additional details about the smart speaker. Now, developer Steve Troughton-Smith has discovered code that seemingly confirms that the upcoming iPhone will support face unlock…

Smith explains that the code indicates the existence of infra-red face unlock in BiometricKit, which is the framework responsible for Touch ID. The code further suggests that Apple’s face unlock feature will be able to detect partially occluded face and faces from various angles. The codename for the project Pearl ID.

The HomePod firmware also includes an image depicting, what we assume to be, the design of the upcoming iPhone Pro, which was discovered by Guilherme Rambo.

Both of these discovered in a file that an Apple employee uploaded to a publicly available server. Hashtag double down on secrecy.
