25 # This podspec searches for the gRPC core library headers under "$(PODS_ROOT)/gRPC-Core", where

29 # symbolic links to the pods headers that Cocoapods creates under "$(PODS_ROOT)/Headers". But those
30 # aren't created when using dynamic frameworks. So our solution is to modify the podspec on the fly
31 # to point at the local directory where the sources are.
