You can add support for Google Protocol Buffers to an Xcode 5 project using Cocoapods by adding the following line to your Podfile.

pod 'GoogleProtobuf', '~> 2.5.0'
This will place the C++ version of the protobuf code into a Pod for your project. It will also add the protoc compiler in the folder Pods/GoogleProtobuf/bin/protoc within your project.

You can create a custom build rule in your project that automatically converts the .proto files into .ph.{h,cc} files. Here is how I did that:

Setup a build rule to "Process Source files with names matching: *.proto Using Custom Script". The script should include the following:

cd ${INPUT_FILE_DIR}
