  s.header_mappings_dir = 'include/grpc'

  # The above has an undesired effect when creating a static library: It forces users to write
  # includes like `#include <gRPC-Cronet/grpc.h>`. `s.header_dir` adds a path prefix to that, and
  # because Cocoapods lets omit the pod name when including headers of static libraries, the
  # following lets users write `#include <grpc/grpc.h>`.
  s.header_dir = 'grpc'

  # To compile the library, we need the user headers search path (quoted includes) to point to the
  # root of the repo, and the system headers search path (angled includes) to point to `include/`.
  # Cocoapods effectively clones the repo under `<Podfile dir>/Pods/gRPC-Cronet/`, and sets a build
  # variable called `$(PODS_ROOT)` to `<Podfile dir>/Pods/`, so we use that.
  #
  # Relying on the file structure under $(PODS_ROOT) isn't officially supported in Cocoapods, as it
  # is taken as an implementation detail. We've asked for an alternative, and have been told that
  # what we're doing should keep working: https://github.com/CocoaPods/CocoaPods/issues/4386
  #
  # The `src_root` value of `$(PODS_ROOT)/gRPC-Cronet` assumes Cocoapods is installing this pod from
  # its remote repo. For local development of this library, enabled by using `:path` in the Podfile,
  # that assumption is wrong. In such case, the following settings need to be reset with the
  # appropriate value of `src_root`. This can be accomplished in the `pre_install` hook of the
  # Podfile; see `src/objective-c/tests/Podfile` for an example.
