A new Swift blog post/announcement has been posted!

Say hello to gRPC Swift 2: a major update that brings first-class concurrency support and more expressive APIs for a seamless developer experience.

Inconsistent and poorly documented service APIs create integration headaches for developers. gRPC is a modern, high-performance framework for building service APIs, enabling efficient communication between systems over a network.

Since services may be written with a different language than their clients, most gRPC services use Protocol Buffers (or “protobufs”) to define their APIs and the messages exchanged between clients and servers. Service contracts are defined in a neutral, cross-platform format using .proto files. This is the foundation of your service, not an artefact of its implementation. And thanks to the format’s efficient binary serialization, these messages are typically smaller and faster to process than other standard formats like JSON.

gRPC Swift is one of a family of similar tools that use the Protocol Buffers contract to generate code in the language you’re working with, making it easy to build clients and servers that adhere to your service contract. And the new gRPC Swift 2 offers an idiomatic, cross-platform, performant and feature-rich library for building highly-scalable services.

This release is a major update that takes advantage of many modern Swift features for cross-platform services development. When gRPC Swift was first developed back in 2018, Swift had not yet introduced concurrency features like async/await, so it was instead based on SwiftNIO’s event-driven concurrency model. For developers unfamiliar with these concepts, the prior version of gRPC Swift presented a steep learning curve. Now that Swift’s modern concurrency model is fully established, we se...
