A plugin and runtime library for using Google's Protocol Buffers with Swift, enabling type-safe serialization.
SwiftProtobuf is a plugin and runtime library that enables Swift developers to use Google's Protocol Buffers for serializing structured data. It generates Swift code from `.proto` schema files, providing type-safe, efficient binary and JSON serialization and deserialization. This solves the problem of safely exchanging data between Swift applications and other platforms using a standardized, schema-driven approach.
Swift developers building applications that need to serialize data for storage, network communication, or interoperability with other systems using Protocol Buffers. It's particularly useful for projects involving cross-platform data exchange or gRPC services.
Developers choose SwiftProtobuf because it offers a native, idiomatic Swift experience with full language integration, high performance, and proven correctness through Google's conformance tests. Its seamless compatibility with the broader Protocol Buffers ecosystem allows easy data exchange with other languages.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Automatically generated code avoids common serialization errors and passes Google's full conformance tests, ensuring data integrity and reliability.
Provides full copy-on-write value semantics, making generated types Hashable and Equatable for seamless use in Swift collections like Sets and Dictionaries.
Binary and JSON serializers are extensively optimized for speed, with methods like .serializedBytes() and .jsonUTF8Bytes() offering efficient data handling.
Same .proto files generate code for multiple languages like Java and C++, enabling consistent data exchange across platforms without extra effort.
Requires building or installing the protoc-gen-swift plugin and Google's protoc compiler separately, adding initial configuration steps and toolchain management.
Relies on specific versions of Swift and protoc, which can lead to compatibility issues, version mismatches, and maintenance overhead, as noted in the system requirements.
Only supports serialization via Protocol Buffers; cannot handle other formats like XML or custom binary protocols without additional libraries or workarounds.
