Use protoc with the Swift plugin to generate Swift files from a .proto file provided by the backend team.

Steps:

1. Download the .proto file provided by the backend team.
2. Rename the file to something descriptive, e.g. ws_chat.proto.
3. Replace the existing .proto file in the project if one already exists.
4. Open Terminal and navigate to the directory containing the .proto file.
5. Run the following command to generate Swift files:

protoc --swift_out=./Generated something.proto

Example:

protoc --swift_out=./Generated ws_chat.proto

This generates a Swift file inside the ./Generated folder that you can drag into your Xcode project.

Rules:

• Never modify the .proto file manually. It is owned by the backend team.
• If changes are required, ask the backend team to update and upload a new version of the Protobuf file.

Tip: Make sure protoc and the Swift plugin (protoc-gen-swift) are installed. You can install them via Homebrew:

brew install protobuf swift-protobuf
