firebase-ios-sdk/Firestore/Protos

Usage

First, make sure you have necessary prereqs for building:

brew install automake libtool protobuf golang

Take a nap while that completes. Then, build the protos:

cd firebase-ios-sdk
mkdir -p build
cd build
cmake ..
make -j generate_protos

Verify diffs, make sure tests still pass, and create a PR.

Script Details

Get the protoc and the gRPC plugin. See here. The easiest way I found was to add pod '!ProtoCompiler-gRPCPlugin' to a Podfile and do pod update.

After running the protoc, shell commands run to fix up the generated code:

• Flatten import paths for CocoaPods library build.
• Remove unneeded extensionRegistry functions.
• Remove non-buildable code from Annotations.pbobjc.*.
