Apple's Swift Protobuf provides a protoc plugin for generating Swift code from .proto files plus the runtime library needed to use that generated code. It supports efficient binary and standards-compliant JSON serialization with idiomatic Swift value semantics.

Use cases

  • serialize Swift structs to protobuf binary format
  • generate Swift code from .proto schema files
  • exchange protobuf messages between Swift and other languages
  • encode and decode protobuf messages as JSON
  • define schema-driven communication protocols in Swift apps

When to choose

  • you need protobuf serialization in Swift or iOS projects
  • you want cross-language message interchange via .proto schemas
  • you need conformance-tested, performant binary and JSON encoding

When to avoid

  • your project does not use Swift
  • you need a serialization format without schema code generation
  • you only need simple JSON without protobuf semantics
