This converter could create a Java POJO using any kind of JSON input. There’s no need to use a custom library for JSON parsing as the default API brings everything we need, from custom key mapping to formatting dates. Like in previous tutorials, we’ll use the super handy JSONPlaceholder API: Please use Geocoder API if you need automatic convert city names and zip-codes to geo coordinates and.

No need to discuss style in code review Saves you time and energy And more. Today let’s look at the simple case of converting an object or struct in our code to & from JSON. It can work with plists as easily as JSON and you can write your own custom encoders & decoders for different formats. That means no more long, ugly toJSON() or init?(json: ) functions.Ĭodable can also replace use of NSCoding when we want to serialize objects to write them to a file and read them back again.
