That’s true; however, adding a second “YourObjectProt" protocol, making YourObject conform to it, adding all of YourObject’s methods into the protocol, and using YourObjectProt as the parameter instead of YourObject, will solve the issue.
Swift wants you to use protocols rather than objects anyway, so perhaps the way to go is to put all the logic in the protocols and protocol extensions, and make MyObject, YourObject, etc, just bare-bones objects (or structs) that just belong to the protocol and don’t do anything else.
