+# 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,

+# 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.
