How are folks using/referencing protobuf generated sources in their projects?

I'm exploring some protobuf interface definitions, but am not super familiar with swift and protobuf - so I wanted to ask how others were managing their proto files and the related generated swift sources.

The proto files in question are from an external project ( and right now I've created another repo ( with the generated sources and scripts to capture them, with the idea that I'll have my own swift package that I can reference and use as a needed that just wraps these definitions. That feels like overkill, but matches a pattern I've used in previous projects (Python focused) when dealing with protobuf definitions.

Any good ways of dealing with this? Or patterns and examples to be recommended?
