A very simple gRPC library to use with Apple's swift-protobuf.
Protobuf outline:
syntax = "proto3";
service HelloService {
rpc Send(HelloRequest) returns (HelloResponse) {}
}
message HelloRequest {
string text = 1;
}
message HelloResponse {
string text = 1;
}Build protobuf file with swift-protobuf-plugin and whatever server-side plugin of your choosing, here I'm using Go:
$ protoc --swift_out=YourSwiftClient/Sources --go_out=plugins=grpc:. your-protobuf-file.proto
Client code:
import Foundation
let url = URL(string: "http://localhost:8080")!
let session = GrpcSession(url: url)
let hello = HelloRequest(text: "Hello, World")
try? session.write(path: "/HelloService/Send", data: hello) { bytes in
let resp = try? HelloResponse(protobufBytes: bytes)
print(resp)
}
