gRPC Swift

This repository contains a gRPC Swift API and code generator.

It is intended for use with Apple's SwiftProtobuf support for Protocol Buffers. Both projects contain code generation plugins for protoc, Google's Protocol Buffer compiler, and both contain libraries of supporting code that is needed to build and run the generated code.

APIs and generated code is provided for both gRPC clients and servers, and can be built either with Xcode or the Swift Package Manager. Support is provided for all four gRPC API styles (Unary, Server Streaming, Client Streaming, and Bidirectional Streaming) and connections can be made either over secure (TLS) or insecure channels.


gRPC Swift has recently been rewritten on top of SwiftNIO as opposed to the core library provided by the gRPC project.

Version | Implementation | Branch | protoc Plugin | CocoaPod | Support --------|----------------|------------------------|-------------------------|-----------------------|----------------------------------------- 1.x | SwiftNIO | main | protoc-gen-grpc-swift | gRPC-Swift | Actively developed and supported 0.x | gRPC C library | cgrpc | proroc-gen-swiftgrpc | SwiftGRPC | No longer developed; security fixes only

The remainder of this README refers to the 1.x version of gRPC Swift.

Supported Platforms

gRPC Swift's platform support is identical to the platform support of Swift NIO.

Note that gRPC Swift uses NIO 2 and therefore requires Swift to be version 5.0 or higher.

Getting gRPC Swift

There are two parts to gRPC Swift: the gRPC library and an API code generator.

Getting the gRPC library

Swift Package Manager

The Swift Package Manager is the preferred way to get gRPC Swift. Simply add the package dependency to your Package.swift and depend on "GRPC" in the necessary targets:

dependencies: [
  .package(url: "https://github.com/grpc/grpc-swift.git", from: "1.0.0-alpha.19")

The syntax for target dependencies changed in Swift 5.2 and requires the package of each dependency to be specified.

For Swift 5.2 (swift-tools-version:5.2):

  name: ...,
  dependencies: [.product(name: "GRPC", package: "grpc-swift")]

For Swift 5.0 (swift-tools-version:5.0) and 5.1 (swift-tools-version:5.1):

  name: ...,
  dependencies: ["GRPC"]

From Xcode 11 it is possible to add Swift Package dependencies to Xcode projects and link targets to products of those packages; this is the easiest way to integrate gRPC Swift with an existing xcodeproj.

Manual Integration

Alternatively, gRPC Swift can be manually integrated into a project:

  1. Build an Xcode project: swift package generate-xcodeproj,
  2. Add the generated project to your own project, and
  3. Add a build dependency on GRPC.


gRPC Swift is currently available from CocoaPods. To integrate, add the following line to your Podfile:

    pod 'gRPC-Swift', '~> 1.0.0-alpha.19'

Then, run pod install from command line and use your project's generated .xcworkspace file. You might also need to add use_frameworks! to your Podfile.

⚠️ If you have conficting modules as a result of having a transitive dependency on 'gRPC-Core' see grpc/grpc-swift#945.

Getting the protoc Plugins

Binary releases of protoc, the Protocol Buffer Compiler, are available on GitHub.

To build the plugins, run make plugins in the main directory. This uses the Swift Package Manager to build both of the necessary plugins: protoc-gen-swift, which generates Protocol Buffer support code and protoc-gen-grpc-swift, which generates gRPC interface code.

To install these plugins, just copy the two executables (protoc-gen-swift and protoc-gen-grpc-swift) that show up in the main directory into a directory that is part of your PATH environment variable. Alternatively the full path to the plugins can be specified when using protoc.

Alternatively, you can get the latest precompiled version of the plugins by adding the following line to your Podfile:

    pod 'gRPC-Swift-Plugins'

The plugins are available in the Pods/gRPC-Swift-Plugins/ folder afterwards.


gRPC Swift has a number of tutorials and examples available. They are split across two directories:

  • /Sources/Examples contains examples which do not require additional dependencies and may be built using the Swift Package Manager.
  • /Examples contains examples which rely on external dependencies or may not be built by the Swift Package Manager (such as an iOS app).

Some of the examples are accompanied by tutorials, including:

  • A quick start guide for creating and running your first gRPC service.
  • A basic tutorial covering the creation and implementation of a gRPC service using all four call types as well as the code required to setup and run a server and make calls to it using a generated client.


The docs directory contains documentation, including:


gRPC Swift is released under the same license as gRPC, repeated in LICENSE.

gRPC Swift 1.0.0-alpha.19 - 2020-08-27 12:37:12

This release includes two sets of breaking changes. The first is a result of performance work on the server, as a result server code must be regenerated. Service provider implementations are not affected by this change. The second breaking change replaces the GRPCStatus.Code enum with an equivalent struct and removes the doNotUse case.

SemVer Major

  • Performance improvements to RPC handling for the server. Note: this changes requires server code to be regenerated. (#924, #925, #931, #932, #935)
  • Turn GRPCStatus.Code into a struct and remove the doNotUse case (#942)

SemVer Patch

  • Fixed a bug where trailers-only responses without a content-type header would result in a status code being syntesized rather than propagating any status code present in the trailers. (#927)
  • Fixed a few incorrect "source" labels emitted in logs (#933)
  • Added additional HTTP/2 information to logs (#938)
  • Allow the gRPC module name to be customised when generating code (#945, #952)
  • Fixed a few edge cases which would lead to a precondition failure in the ConnectionManager (#950, #953)
  • Update NIO version to 2.22.0 and NIOHTTP2 to 1.14.1. (#954)
  • Added SwiftFormat to CI and baselined the existing codebase (#929, #936)

Other Changes

  • Update the quick start guide (#940, patch credit to @kingkangyu)
  • Various CI improvements (#923, #934, #936)
  • Update information relating to Cocoapods in README (#943, #944)
  • Fixed a performance benchmark (#948)

gRPC Swift 1.0.0-alpha.18 - 2020-08-07 08:51:08

This release includes breaking changes to the ServerErrorDelegate protocol. The functions transformLibraryError(_:) and transformRequestHandlerError(_:) now return the GRPCStatus and HTTPHeaders: this allows users to send additional metatada to clients. The original API returning just GRPCStatus has been deprecated and will be removed prior to 1.0.0.

As part of this release, gRPC will no longer log by default. A logger must be provided to gRPC in order for logs to be emitted.

SemVer Major

  • Allow the server error delegate to return HTTPHeaders in addition to the gRPC status in order to allow for additional metatada to be sent to the client. (#873, patch credit to @FranzBusch)

SemVer Minor

  • Added configuration to allow for loggers to be specified on the client and server (#902)
  • Added configuration to allow clients and servers to provide a debugging channel initializer (#908, #911)

SemVer Patch

  • Mitigate an issue where insecure connections using Network.framework may stall in the event of zero-length writes. (#917)
  • Removed some unnecessary copy-on-writes (#906)
  • Reduced code duplication between builders and configuration (#907)
  • Update to SwiftNIO HTTP/2 1.13.0 (#922)
  • Switch a numericCast to the required type (#920)

Other Changes

  • Various Cocopods fixes (#898, #916)
  • Various testing and CI improvements (#919, #910, #905, #903)

gRPC Swift 1.0.0-alpha.17 - 2020-07-16 09:36:30

This release includes changes to how gRPC Swift supports SwiftProtobuf messages. As such service code will need to be regenerated.

gRPC Swift provides support for any message types conforming to the GRPCPayload protocol. SwiftProtobuf.Message followed the same code path as all other message types and required conformance to GRPCPayload. This was done by generating conformance to GRPCProtobufPayload which provided a default implementation of the methods required by GRPCPayload for SwiftProtobuf.Messages. However, generating this conformance caused numerous issues and required the user to pass their message definitions to the gRPC code generator. As such we now support SwiftProtobuf.Message separately to GRPCPayload: generating conformance to GRPCProtobufPayload is no longer required and users are no longer required to pass their message definitions to the gRPC code generator; only their service definitions.

SemVer Major

  • Support SwiftProtobuf.Message without requiring GRPCProtobufPayload conformance. This change will require users to regenerate their code in order to remove the now redundant conformance. (#886, #888, #889, #894)

SemVer Minor

  • Add support for ping-based keepalive to both client and server. (#850, #893, patch credit to @SebastianThiebaud)

SemVer Patch

  • Fix an aggressive assert which cause a fatal error when using NetworkPreference.best on older platforms (#896)

Other Changes

  • Reduce the size of input in some tests (#890)

gRPC Swift 1.0.0-alpha.16 - 2020-07-08 08:28:06

This release includes a few breaking changes in order to enable API evolution in the future.

SemVer Major

  • Turn NetworkImplementation and NetworkPreference enums into structs. This will only affect users switching over these types. (#866)
  • Remove GRPCStreamType public enum which was only used as part of an error type. (#880)

SemVer Patch

  • Fixed a bug where clients may hit a preconditon failure on idle connections. (#875)
  • Fixed a bug where payload conformance would not be generated for nested messages. (#879)
  • Provide a new codegen option to allow test clients to be generated separately from real clients. (#881)

Other Changes

  • Fix incorrect documentation for certificate verification on the server builder (#882)
  • Remove 'nio' tag from Issue templates (#876)

gRPC Swift 1.0.0-alpha.15 - 2020-07-03 14:42:31

This release includes a number of breaking changes. The most important of which are detailed below:

  1. Timeouts. The CallOptions.timeout property has been deprecated in favour of timeLimit which allows either a timeout or a deadline to be set. The type used for timeouts has changed from GRPCTimeout to SwiftNIO's TimeAmount for better compatability with the rest of the Swift on Server ecosystem.
  2. API evolution changes. A number of public enums have been converted into public structs. At the call-site this change will not impact users. This change will break users who previously switched over these enums. Changed types include RequestIDProvider, ConnectionTarget, and Compression. In addition, the client call implementations were reworked and the BaseClientCall class was removed as a result.

This release also includes a number of changes to the generated code, including the ability to generate test clients.

SemVer Major

  • Allow deadlines or timeouts to be set on RPCs. The timeout option on CallOptions has been replaced with timeLimit. (#842)
  • Replace a number of public enums with struct in order to make the API more evolvable in the future. This includes RequestIDProvider, ConnectionTarget, and Compression. This will only affect users who switch over these cases. (#839, #861, #867)
  • Provide an internal transport abstraction for client RPCs. The user facing impact is the removal of the BaseClientCall class. (#834)

SemVer Minor

  • Added an 'isOk' to property to GRPCStatus (#840)
  • Added a configuration option to allow the connectivity state delegate DispatchQueue to be specified (#849)
  • Added a configuration option which allows users to 'fast-fail' an RPC rather than waiting for a active connection (#860)
  • Added an option to the code generator to enable users to generate 'test clients' (#855, #864, #870, #856, #865)

SemVer Patch

  • Provide more specific errors to failed promises on calls rather than the error status (#859)
  • Fix a bug which prevented the user-agent header being overridden via user provided customMetadata (#845, patch credit to @ikait)
  • Fixed a race condition when scheduling a timeout on an RPC (#847)
  • No longer send requests in a call object initialisation (#848)
  • Remove a warning from a now-redundant try (#871)

Other Changes

  • Fix a Cocoapod version issue in one of the examples (#851, patch credit to @zhungxd)
  • Add a generation of the gRPC-Swift-Plugins.podspec (#869, patch credit to @Lutzifer)
  • Make language more inclusive (#841)

gRPC Swift 1.0.0-alpha.10 - 2020-03-19 13:09:41

⚠️ This release contains a number of API breaking changes. ⚠️

In order to support payloads other than Protocol Buffers, for example Flatbuffers, it was necessary for much of the surface API to be generic over a new protocol, GRPCPayload instead of Message. This therefore requires that services are regenerated.

We also took this opportunity to address the interface between the generated code and runtime library: clients previously relied on ClientConnection for transport, they now rely on an something conforming to GRPClient; such as ClientConnection.

Generated clients have also had "Service" removed from their name. For example, the client for the Bar service in the Foo package would previously have been generated as Foo_BarServiceClient and will now be generated as Foo_BarClient. If you have multiple references to generated clients in your code which need updating it is possible to create a deprecated type alias such that Xcode will provide fixits:

@available(*, deprecated, renamed: "Foo_BarClient")
typealias Foo_BarServiceClient = Foo_BarClient

The list of supported platforms has now been added to Package.swift; dependents using Swift Package Manager must now also declare their supported platforms.

SemVer Major:

  • Adds the ability to use different payloads (#710, patch credit to @mustiikhalil)
  • Rename generated clients from FooServiceClient to FooClient (#736)
  • Put the client connection behind a protocol (#727)
  • Add supported platforms to Package.swift (#696)
  • Add support for compression (#714, #707, #729)
