Serialization in Swift

A way to specify nested fields more easily. Currently in the Codable API, we have to define separate data types to handle the nesting structure in a JSON object. Sometimes I want to flatten the structure on the client side (e.g. for better uniform representation, easier to do some abstraction), but it may be difficult (or impossible) to let server guys do the flattening logic for me. So I'd prefer that there will be rather easy way to specify a nested field (like @field("outerObj.innerObj.modifiedDate") var modifiedDate: Date? ). This could save me a lot of time.
