I'm afraid we dropped Cocoapods support in 2.40.0. |

## Summary This PR introduces support for the vanilla gRPC protocol by providing a new `ConnectNIO` library which utilizes `SwiftNIO` (which provides support for trailers) to expose a new `.grpc` extension on `NetworkProtocol`. Note that this new library is not available through CocoaPods because [SwiftNIO no longer supports CocoaPods](apple/swift-nio#2393). ## Details - In order to avoid requiring consumers who are using the Connect or gRPC-Web protocols to depend on `SwiftNIO`, a new `ConnectNIO` module is being introduced alongside the existing `Connect` module. This means that existing Connect/gRPC-Web users do not need to include this new dependency. - This module contains a new `NIOHTTPClient` type which wraps `SwiftNIO` concepts and conforms to `Connect.HTTPClientInterface`. - The `ConnectNIO` module also contains logic to support gRPC, which is exposed as an extension on `NetworkProtocol` (demonstrated below). - Consumers who want to use the NIO-based HTTP implementation with other protocols can accomplish this by including `ConnectNIO` and replacing `URLSessionHTTPClient` usage with `NIOHTTPClient`. ## Example The Eliza Swift Package Manager example has been updated to include support for gRPC using the `NIOHTTPClient`. Using gRPC with generated Connect clients is as easy as adding an import and making a 2-line change: ``` import Connect import ConnectNIO // Include NIO and gRPC support ... let protocolClient = ProtocolClient( httpClient: NIOHTTPClient(host: "https://demo.buf.build"), // Use NIO config: ProtocolClientConfig( host: "https://demo.buf.build", networkProtocol: .grpc, // Use gRPC codec: ProtoCodec() ) ) ``` ## Binary size impact **There is no binary size impact on clients that only include the `Connect` library.** When including `ConnectNIO`, `SwiftNIO` dependencies get compiled in, resulting in a ~2.1MB increase on an unstripped `.ipa`. For example: - Eliza app with `Connect`: 699KB - Eliza app with `ConnectNIO`: 2.8MB ## Testing The suite of crosstests has been updated to run a matrix of tests which include: - Connect + (JSON & Proto binary) using (`URLSessionHTTPClient` & `NIOHTTPClient`) - gRPC-Web + (JSON & Proto binary) using (`URLSessionHTTPClient` & `NIOHTTPClient`) - gRPC + (JSON & Proto binary) using (`NIOHTTPClient`)

The podspecs for several NIO libraries are a few versions out of date:
It looks like this has happened before (#1017, #1390, #2052) - would it make sense to automate this and/or make it part of the release process?
Thanks!
