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.
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.*.
