Big thanks to Webkul and his team for helping get Opencart 184.108.40.206 release ready!
Updated 22 November 2019
Apple has launched the new feature in Swift to parse JSON Swift Codable protocol. Swift 4 has introduced standard Codeable protocol which is part of the Foundation framework and JSON parsing became a single or couple of lines of code.
The Codable is a combination of two protocols, Decodable and Encodable. init(from: Decoder) and encode(to: Encoder) respectively. In other words, for a type to be “decodable” or “encodable”, they’ll need to “decode from something” and “encode to something”.
The real magic of Codable happens with the Decoder and Encoder protocols. The JSONDecoderand JSONEncoder classes use those two protocols to provide the functionality to decode/encode JSON.
1-> Mismatch between the strong data types of Swift and lose data types of JSON has been internally handled by the Swift compiler. We can now handle Swift Data types like Date, URL, Float, etc
2-> Using Codable we can make the app faster. because with hel of codeable we don’t need to worried about Complex JSON and with codeable easily managed by Nesting Structure.
3-> For array JSON you don’t need to use any loop for store the data in an array object.
4-> USing Codeable we can model JSONObject or PropertyList file into equivalent Struct or Classes by writing very few lines of code
->After run the project you will get this output.
->Now you can get an index value with the help of your defined keys.
