Serialization in Swift

When I want to specify date formatting, the existing Codable API only allows me to set dateEncodingStrategy on the JSONEncoder object. In most scenarios which I have encountered the date formatting logic should only be written once (in the data type definition I suppose), but the current Codable API requires every use site of the data type specify the rule (which could easily be got wrong or just forgotten in the copy&paste process). Much worse is that we can't specify two different dateEncodingStrategy on two different properties in a single data type (the data field may come from sub systems, and it should be easier to write this behavior on the client than to persuade server guys to change their logic).

I'v seen this one (and similar) solved with property wrappers. what do folks think about that solution?
