YYModel is a high-performance JSON-to-model conversion framework for iOS and macOS written in Objective-C. It converts between JSON/dictionaries and native model objects with automatic type conversion, type safety, and no need for base-class inheritance.

Use cases

• convert JSON API responses into Objective-C model objects
• serialize model objects back to JSON dictionaries
• map nested JSON structures to nested model classes
• automatically convert types like strings to dates or numbers
• replace slow reflection-based JSON mapping with a faster library
• parse JSON into models without inheriting from a base class

When to choose

• you are building an iOS or macOS app in Objective-C or Swift that consumes JSON APIs
• you need extremely fast JSON-to-model conversion close to handwritten performance
• you want a lightweight, non-intrusive library with only a few files
• you need robust automatic type conversion between JSON and Objective-C types

When to avoid

• you are not targeting Apple platforms
• you prefer Swift-native Codable for JSON handling in a pure Swift codebase
• you need cross-platform serialization beyond iOS/macOS
• the project requires actively maintained dependencies with frequent updates
