# Calling the Google Cloud Natural Language API

This directory contains a very simple sample that calls the 
[Google Cloud Natural Language API](https://cloud.google.com/datastore/docs/reference/rpc/google.datastore.v1).
Calls are made directly to the Cloud Natural Language RPC interface. 
In practice, these would be wrapped in idiomatic code.

1. Run `pod install` to install the SwiftGRPC pod and its dependencies.

2. Running `pod install` will invoke [RUNME](RUNME) to generate the 
necessary Protocol Buffer and gRPC support code. It uses protoc and 
the Swift Protocol Buffer and gRPC plugins, so please be sure these 
are in your path. The plugins can be built by running `make` in the 
top-level grpc-swift directory.

3. Open NaturalLanguage.xcworkspace and set GOOGLE_API_KEY in the application delegate.

4. Run the app.

## Prerequisites

This sample requires a Google Cloud Platform account and an API key
for the Cloud Natural Language service.
