Usage

First, make sure you have necessary prereqs for building: brew install automake libtool protobuf

Take a nap while that completes. Then, build protobuf and nanopb: cd firebase-ios-sdk mkdir -p build cd build cmake .. make -j protobuf nanopb

Next, build the protos: cd firebase-ios-sdk/Firestore/Protos ./build-protos.sh

Verify diffs (you'll likely need to re-add copyright notices, etc.), 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.*.
