If you are using the iso8601 strategy, you may not want to rely on the default Equatable implementation for Date (==) when comparing dates. You can use a good old fashion calendar comparison instead.


JSONEncoder and JSONDecoder can both be configured with a strategy (dateEncodingStrategy and dateDecodingStrategy) for encoding and decoding dates. There are four named types in addition to allowing you to provide custom options.
