Domine el protocolo Codable de Swift. Convierta muestras de JSON directamente en structs de Swift listos para ser usados en sus aplicaciones de Apple, simplificando enormemente el parsing de datos desde servicios web y bases de datos.
Automating the conversion of JSON payloads into strictly typed Swift definitions saves hours of boilerplate coding and reduces type errors.
Your JSON data is parsed and converted entirely inside your browser. No data is ever sent to a server, ensuring your payloads remain 100% private.
El protocolo `Codable` revolucionó el manejo de JSON en Swift. Nuestra herramienta genera structs que implementan este protocolo por defecto, manejando correctamente fechas, URLs y tipos opcionales de forma idiomática.
Cree modelos de vista (ViewModels) más rápido. Al generar sus tipos de datos automáticamente, puede centrarse en construir interfaces de usuario impresionantes con SwiftUI o UIKit en lugar de escribir código de infraestructura.
Pegue su objeto JSON en el panel de la izquierda.
El código se genera automáticamente en tiempo real.
Copie el resultado final directamente al portapapeles.
Sí, si los nombres de los campos JSON no siguen la convención camelCase de Swift, generamos el enum `CodingKeys` correspondiente.
Sí, identifica automáticamente qué campos pueden ser nulos basándose en los datos proporcionados.
Absolutamente. El procesamiento ocurre íntegramente en su navegador y el código es seguro.
Transforming and parsing JSON safely into Swift types is a crucial task for maintaining data integrity in your application. Doing this manually inevitably leads to subtle type errors, missed fields, and unstable parsing behavior—especially in large architectures with deeply nested objects. This tool generates reliable, production-ready Swift models based directly on your provided sample schemas.
In modern software engineering, type-safe data handling is no longer optional. When your application consumes external data, having a strict Swift contract ensures that your IDE can provide better autocompletion and that your compiler can catch potential runtime errors before they affect users. This utility infers types, handles optional fields, and manages naming conventions (like camelCase vs snake_case) to provide a seamless transition from raw JSON to structured Swift code.
FmtDev is built for developers who handle sensitive data. All JSON parsing and Swift code generation happens entirely on the client side. No data is ever transmitted to our servers, ensuring your JSON payloads remain confidential. This architecture not only protects your intellectual property but also ensures the tool remains functional even in offline environments or strict network-locked corporate workspaces.
Simply paste your JSON payload into the input area. The tool analyzes the structure and instantly produces the corresponding Swift definitions. By automating this structured output process, developers can remove human-error from payload consumption, ensure strict typing constraints, and greatly reduce application runtime crashes resulting from malformed network responses.
