Prompt Preview

Apply these rules to existing gRPC Swift 1.27.6 GRPC integrations and protoc-gen-grpc-swift output with the included Swift 6.3 baseline. Swift 6.4 has shipped, so the published v1 support table now places gRPC Swift 1.x outside support; keeping a Swift 6.3 compiler does not extend it. Plan migration to maintained gRPC Swift 2 APIs and deployment requirements while preserving authentication, transport security and resource limits on every legacy listener. This package policy does not establish the compiler line's own maintenance status.

Runtime and generated code

  • Keep application targets in Swift 6 language mode, but account for this dependency's Swift tools 6.1 minimum and explicit Swift 5 language mode. A Swift 6.3 compiler does not make gRPC's event-loop-confined objects safe to share across tasks.
  • Keep protoc-gen-grpc-swift on the same release as the GRPC runtime and move them together; code generated by a newer 1.x generator has no compatibility guarantee with an older runtime. Review the paired protoc-gen-swift, .proto changes, and regenerated interceptor factories before deployment.
  • Retain the production Package.resolved and check swift-nio, swift-nio-http2, and, when included, swift-nio-ssl separately from gRPC: this release's declared dependency minimums admit versions older than published SwiftNIO fixes, and vulnerability scanners miss some SwiftNIO advisories. Before each release, compare the resolved versions with the fixed releases listed on each project's GitHub security advisory page and move to them with
