A magical data modeling framework for JSON that automates model creation and validation for iOS, macOS, watchOS, and tvOS apps.
JSONModel is a data modeling framework for Objective-C that automates the mapping of JSON data to native model objects. It eliminates manual parsing code by introspecting model classes and converting JSON values to the correct property types. The framework handles validation, optional properties, nested models, and custom transformations.
iOS, macOS, watchOS, and tvOS developers working with JSON APIs who want to reduce boilerplate parsing code and ensure type-safe data models.
Developers choose JSONModel because it dramatically reduces the amount of code needed to parse and validate JSON, provides automatic type conversion, and supports complex scenarios like nested models and custom mappings while being lightweight and focused on the Apple ecosystem.
Magical Data Modeling Framework for JSON - allows rapid creation of smart data models. You can use it in your iOS, macOS, watchOS and tvOS apps.

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.
Primarily designed for Objective-C; it lacks native Swift support and modern features like Codable, requiring bridging in Swift projects which adds complexity.
Requires protocols for model collections, which can be confusing and conflict with Objective-C generics, as noted in the README's model collections example with NSArray <ProductModel>.
Relies on runtime introspection for property mapping and validation, introducing performance penalties compared to compile-time solutions like Swift's Codable in some scenarios.
