What Is XML to Swift?

Writing Swift models by hand from an XML response is slow and error-prone — especially when you're dealing with nested elements across dozens of fields. Swift uses XMLParser or XMLDecoder for XML parsing, and this tool scaffolds the structs automatically so you can start coding faster. The output targets both iOS and macOS apps, with optional Codable conformance. The W3C XML specification defines the format — and everything runs in your browser via the DOMParser API. Nothing leaves your machine.

How to Use This Tool

1

Paste or Upload XML

Paste XML or upload a file. Set struct name, Use Codable, and Optional Types in the config.

2

Review Swift Output

The right panel shows generated structs. Use XMLParser or XMLDecoder to parse and populate.

3

Copy or Download

Use Copy or Download. For JSON to Swift, use JSON to Swift. For XML formatting, use XML Formatter.

When XML to Swift Helps

When building iOS or macOS apps that consume XML APIs or config, generate structs here. Use XMLParser or XMLDecoder to parse.

Frequently Asked Questions

Does Swift's Codable work with XML?

Swift's Codable protocol mainly targets JSON. XMLDecoder exists in Foundation but has limited support for attributes. For full XML parsing, XMLParser with manual delegate methods is the standard approach. Enable Use Codable in this tool if your setup uses XMLDecoder.

How do I use the generated Swift structs with XMLParser?

Implement XMLParserDelegate in your class, then use didStartElement, foundCharacters, and didEndElement callbacks to populate the struct fields. The generated struct gives you the exact property names to target. See the XMLParser docs for full details.

Can I use this for SwiftUI data models?

Yes. The structs work as plain Swift value types you can use in any SwiftUI or UIKit app. Mark them @Observable or wrap in an ObservableObject to bind them to your views.

What about nested XML elements?

Nested XML elements are mapped to nested Swift structs. Each child element becomes its own struct, mirroring the XML hierarchy. This keeps your model clean and type-safe.

Is my XML data sent to a server?

No. All processing runs locally in your browser using the DOMParser API. Nothing is uploaded or stored anywhere.
