Modification: The code generator imports SwiftProtobuf if the file being generated has a dependency on any of the protos bundled by SwiftProtobuf. This can yield unnecessary imports which may warn if used in conjunction with access levels on imports. The problem is that the grpc generator checks for dependencies on the FileDescriptor which may include messages defined in the same file as a service. If any of those messages depend on a well known type (WKT) then an import will be added even though the code being generated doesn't include message code. Modifications: - Only include a SwiftProtobuf import if an input or output type for an RPC is a bundled proto. - Fix a test where a WKT is used in a message but not as an input/output type for an RPC. Result: Fewer warnings
