  • This variable holds an instance of the PassiveFaceCaptureModel.

    Declaration

    Swift

    var model: PassiveFaceCaptureModel

  • This variable holds an instance of the FaceScannerController.

    Declaration

    Swift

    var faceScanController: FaceScannerController

  • The passive face capture session.

    Declaration

    Swift

    var session: PassiveFaceCaptureSession?

  • Callback for handling session errors.

    Declaration

    Swift

    var onSessionError: ((_ model: PassiveFaceCaptureModel) -> Void)?

  • Callback for updating instructions. Usually subscribed by the view.

    Declaration

    Swift

    var onInstructionUpdate: ((_ model: PassiveFaceCaptureModel) -> Void)?

  • Callback for handling session completion. Usually subscribed by the view.

    Declaration

    Swift

    var onSessionCompleted: ((_ model: PassiveFaceCaptureModel) -> Void)?

  • Lock object for thread safety.

    Declaration

    Swift

    let lock: Lock

  • This function initializes the model and sets the frame captured callback.

    Declaration

    Swift
