What is JSON to Swift Struct?
JSON to Swift struct tool can automatically generate Swift structs conforming to the Codable protocol based on JSON data. Generated code includes correct type annotations, CodingKeys enumeration (for mapping JSON keys to Swift properties), and proper handling of nullable values. The tool supports nested object generation for nested structs, and array types automatically convert to Swift arrays. Generated code can be directly used for JSON parsing in iOS/macOS development.
When to Use JSON to Swift Struct
Use when parsing JSON APIs in iOS/macOS application development, creating data models, working with URLSession and JSONDecoder, or accelerating Swift backend development.
