Question Subject

CocoaPods Support for NIO implementation

Question Description

Hi! I thought this might have been asked before but issue search said 'not really'.
GRPC-swift is the main dependency on a project I'm maintaining Zcash iOS SDK

we serve static assets, which is not supported by SPM and most of our users have reported using cocoapods as their dependency manager of choice.

I'm wrapping my head around contributing with such support, on this project but it is unclear to me the tasks involved, because it's not evident to me which dependencies of this new implementations already have cocoapods support and which do not. I assume that main contributors like @MrMage might already have an idea of the effort and tasks needed for doing this.

I think we already have a PR pending for CocoaPods support, courtesy of @Jake-Prickett: #764

Thank you @MrMage for your quick response.
