JSON to Swift Codable

Generate Swift Codable structs from JSON. Use with JSONDecoder at the API boundary; the compiler enforces shape at compile time. ISO 8601 dates become Date (configure your decoder's dateDecodingStrategy to .iso8601).

How to use the JSON to Swift Codable

Paste JSON. Output is ready to drop into your iOS / macOS app. For snake_case JSON keys, set JSONDecoder().keyDecodingStrategy = .convertFromSnakeCase and use camelCase field names in Swift.
