# gRPC-Core.podspec needs to be modified to be successfully used for local development. A Podfile's
# pre_install hook lets us do that. The block passed to it runs after the podspecs are downloaded
# and before they are installed in the user project.
#
# This podspec searches for the gRPC core library headers under "$(PODS_ROOT)/gRPC-Core", where
# Cocoapods normally places the downloaded sources. When doing local development of the libraries,
# though, Cocoapods just takes the sources from whatever directory was specified using `:path`, and
# doesn't copy them under $(PODS_ROOT). When using static libraries, one can sometimes rely on the
# symbolic links to the pods headers that Cocoapods creates under "$(PODS_ROOT)/Headers". But those
# aren't created when using dynamic frameworks. So our solution is to modify the podspec on the fly
# to point at the local directory where the sources are.
#
# TODO(jcanizales): Send a PR to Cocoapods to get rid of this need.
