Build real-time apps and services with gRPC and Swift

A Podkey summary of Build real-time apps and services with gRPC and Swift, from WWDC 2026.Today’s catch-up is really about one idea from a few angles: gRPC Swift is a lot more than a niche networking tool, and the case for it gets stronger once you care about performance, streaming, and real app behavior. There’s a clear contrast with OpenAPI and REST, a practical story around protobuf efficiency, and some very usable lessons on client reuse, deployment, and production features. And maybe the biggest signal is that Apple is using this stuff all over the place, which usually gets people’s attention pretty fast.gRPC versus OpenAPI in SwiftWhy protobuf helps so muchThe four streaming patternsA practical SwiftUI lessonHow the bidirectional stream works under the hoodFrom Swift server to production containerWhere Apple is already using itThe wider gRPC Swift ecosystemThis podcast was created with Podkey.
