Testing gRPC for a small part of my iOS/iPadOS app. I already did some image resource fetching using Protobuf and it's working fine. It's however not a solution that scales too well as it's only one request in flight at one time. So rather than invent an own multiplexing I'll see how gRPC would work.
Perhaps my entire backend could be gRPC one day, but that's a bit of work as it's some 100+ endpoints...
