We have to do some adjustments in swift/java code for android/ios for our internal purposes. What are steps for building an library and use them in react-native projects? We are on macs … we tried python3 build-webrtc.py --setup --android ../src/ for example, but if stuck frozen. We just cloned whole project, run npm install on root and did that command. Without any change in code. Is there somewhere an tutorial how we can achieve that, or at least steps to build it?
