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) }
