JSONModel

Maps JSON keys to model properties based on naming conventions, drastically reducing boilerplate code—as shown in the basic usage example where no implementation file code is needed.

Automatically converts JSON values (e.g., strings to integers, numbers to strings) to expected Objective-C types, demonstrated in the CountryModel example with id and dialCode.

Handles complex JSON structures through model cascading and collections, allowing properties to be other JSONModel instances or arrays, as illustrated with OrderModel and ProductModel.

Enables mapping JSON keys with different names or nested paths using keyMapper, useful for APIs with inconsistent naming like snake_case, shown in the nested key mapping example.
