  An internal-only pod containing the TensorFlow Lite C library that the public
  `TensorFlowLiteSwift` and `TensorFlowLiteObjC` pods depend on. This pod is not
  intended to be used directly. Swift developers should use the
  `TensorFlowLiteSwift` pod and Objective-C developers should use the
  `TensorFlowLiteObjC` pod.
