How do I convert JSON to SWIFT using this tool?

Paste your JSON into the left editor, select JSON as the source and SWIFT as the target format, then click 'Convert'. The output Swift structs appear instantly in the right panel. Copy the generated code and paste it into your Xcode project to start decoding.

Why should I convert JSON to SWIFT?

Converting JSON to Swift is essential when building iOS apps. JSON only describes data, while Swift provides a type-safe model layer. This conversion generates Codable structs automatically, so you can decode API responses without manual or error-prone mapping, saving development time and runtime bugs.

How does the tool handle nested arrays, optionals, and other JSON attributes in Swift?

The tool handles every JSON value: nested objects become Swift structs, arrays become [Element], strings become String (or Date if a custom format is detected), and absent keys are mapped to optionals. The generated code conforms to Codable, so decode and encode are automatically supported.

Is JSON-TO-SWIFT free to use?

Yes, JSON-TO-SWIFT on LetsConvert is 100% free with no registration or hidden fees required.

Are my uploaded files safe and secure?

Yes! File privacy and security are guaranteed. Basic conversions run locally in your browser. Files sent for server processing are automatically deleted within 1 hour.

Does this converter work on mobile phones and tablets?

Yes! JSON-TO-SWIFT works seamlessly across iPhone, Android, iPad, Mac, Windows, and Linux browsers without installing any app.

Is there any software installation required?

No software or browser extension installation is needed. All conversions are performed directly online.
