Type 'Foo' does not conform to protocol '_MessageImplementationBase'

[AaronTriplett]

Extensions for each message type in my generated pb.swift files do not conform to the _MessageImplementationBase protocol. Looks like they are missing the _protobuf_generated_isEqualTo function.

I am generating these outside of my project using the following:
protoc 3.5.1
protoc-gen-swift 1.1.1
protoc-gen-swiftgrpc master

Looks like this issue is caused due to me building the protoc-gen-swift and protoc-gen-swiftgrpc plugins using the master branch, which includes swift-protobuf 1.1.1. However, when including the SwiftGRPC dependency in my podspec, it grabs the latest 0.5.1 release which uses swift-protobuf 1.0.3.

Swift-protobuf 1.1.1 updates the _MessageImplementationBase protocol to include a default implementation extension for the _protobuf_generated_isEqualTo function. Using plugins built from master, the method doesn't get added to my generated message types because the SwiftGRPC (0.5.1) dependency in my podspec doesn't have the default implementation included in its swift-protobuf 1.0.3 dependency.

Building the plugins from 0.5.1 resolves my issues. Any chance a new release will be cut soon that includes swift-protobuf 1.1.1?

Thanks for the heads-up! Given that this is a breaking change, we should indeed cut a new release. I've created #303 now. Once that has been approved by @timburks, I can merge it and update the CocoaPods repo.

Great 👍

I have pushed 0.6.0 to CocoaPods now; please let me know if the issue occurs again.
