We also get all the advantages of working with protocol buffers, including efficient serialization, a simple IDL, and easy interface updating. To download the example, clone the grpc repository by running the following commands:.

You also should have Cocoapods installed, as well as the relevant tools to generate the client library code and a server in another language, for testing. You can obtain the latter by following these setup instructions. To try the sample app, we need a gRPC server running locally. Finally, open the XCode workspace created by Cocoapods, and run the app. You can check the calling code in ViewControllers. The next sections guide you step-by-step through how this proto service is defined, how to generate a client library from it, and how to create an app that uses that library.

A gRPC service and its method request and response types using protocol buffers. You can see the complete. Then you define rpc methods inside your service definition, specifying their request and response types. Because of this, both beginners and experienced programmers alike can use this book to quickly and effectively learn the fundamentals of Objective-C. Readers can also learn the concepts of object-oriented programming without having to first learn all of the intricacies of the underlying C programming language.
