Swift gRPC API

This repository contains an experimental Swift gRPC API.

Not yet intended for production use, it provides low-level Swift wrappers for the C gRPC API that can be used to build higher-level structures supporting streaming and nonstreaming gRPC APIs.

Temporary protocol buffer support is provided in the QuickProto library. This simple Swift library provides an API for building and parsing protocol buffers with no generated code.

Code is provided for both gRPC clients and servers, and it can be built either with Xcode or the Swift Package Manager. The Xcode build is demonstrated with Echo, a sample Mac app that can be used to run echo clients and servers with streaming and nonstreaming interfaces over secure (TLS) and insecure channels.

Other examples include Sessions, StickyNotes, and Speech.

Swift Package Manager builds are demonstrated on Linux using the instructions in the Packages directory. (Linux builds are currently untested and were presumed broken by the addition of Grand Central Dispatch APIs for streaming API support; they will be fixed when threading-related incompatibilities between Linux and Darwin are resolved).

Can't find something?

It was harder to get the Swift package manager to deal with code in outside directories than to point Xcode at them, so you'll find the code for gRPC, CgRPC, and QuickProto in the Sources directory associated with each package.
