GRPC prbc.h classes not generated objective-c - objective-c

Question

I am trying to use GRPC with react native. While basic helloWorld example is working fine with it. When i Added new request to hellowWorld.proto file its is not generating/updating Helloworld.prbc.h file.
helloworld.proto
syntax = "proto3";
option objc_class_prefix = "HLW";
package helloworld;
// The greeting service definition.
service Greeter {
// Sends a greeting
rpc SayHello (HelloRequest) returns (HelloReply) {}
rpc HelloDev (HelloDevRequest) returns (HelloDevReply) {}
}
// The request message containing the user's name.
message HelloRequest {
string name = 1;
}
// The response message containing the greetings
message HelloReply {
string message = 1;
}
// The request message containing the user's name.
message HelloDevRequest {
string name = 1;
}
// The response message containing the greetings
message HelloDevReply {
string message = 1;
}
I tried:
pod install
after pod install i was expecting Helloworld.prbc.h to have defination for HelloDev.
Another way:
protoc --objc_out=Pods/ReactNativeGrpc --objcgrpc_out=Pods/ReactNativeGrpc helloworld.proto
ReactNativeGrpc is pod for my project
here is auto generated file from compiler (its same even after running pod install)
// Code generated by gRPC proto compiler. DO NOT EDIT!
// source: helloworld.proto

Want to use updated proto definition in code, that's not working here.
Edit 1: Cleaning and installing every time works but need alternative to avoid it.

Answer 1

Have you tried to clean Cocoapods cache? If not, try to run the following command to clean cache before running pod install:
rm -rf Pods
rm -rf (your_project).xcworkspace
rm Podfile.lock
