XML to Swift Converter

XML is a attribute-rich, namespace-aware hierarchical document format — widely used for SOAP APIs, RSS/Atom feeds, Android layouts, enterprise data exchange. Converting it to strongly-typed Swift structures eliminates runtime surprises and speeds up development. This tool does it in one click, entirely in your browser.

How to use this converter

1. Paste your XML into the left editor panel
2. Click Generate
3. Copy the generated Swift code from the right panel

No account. No upload. No tracking. Runs entirely in your browser.

The problem with manual XML-to-Swift mapping

Swift is a type-safe, protocol-oriented language — typed data models are central to how it works. Yet copying fields from XML payloads into Swift struct / Codable definitions introduces subtle errors:

• Mistyped field names cause silent deserialization failures
• Missing optional fields trigger runtime panics or null errors
• Schema drift between API and model goes undetected until production

Swift's Codable protocol (combining Encodable and Decodable) enables automatic JSON/XML parsing with zero boilerplate.

This converter eliminates the manual step entirely.

Swift and XML: what you need to know

Swift is a type-safe, protocol-oriented language, required for iOS, macOS, and Apple platform development. It uses struct and Codable protocol based for structured data — making it a natural fit for XML-driven applications.

What the converter generates

The output consists of Swift structs conforming to Codable with CodingKeys where needed. This is the idiomatic pattern for Swift data models, compatible with popular Swift serialization libraries.

A common gotcha

Swift's Codable fails silently on missing required fields — mark optional fields as Optional to avoid decoder crashes.

XML input characteristics

XML allows mixed content (text + child elements), namespaces, and CDATA sections — more expressive but more verbose than JSON. XML is the foundation of many enterprise integration standards including XSLT, XSD, and SOAP.

Common use cases

• Validating XML contract compatibility with Swift type definitions
• Generating Swift models from iOS apps API responses
• Creating typed DTOs for macOS utilities
• Rapid prototyping with real XML payloads
• Keeping Swift structs in sync when XML schemas evolve
• Onboarding new team members by auto-generating the data layer

Frequently asked questions

Is my XML data sent to a server?

No. All conversion runs locally in your browser using client-side JavaScript. Your XML data never leaves your machine.

What XML inputs does this converter accept?

Paste any valid XML — including SOAP APIs, RSS/Atom feeds, Android layouts, enterprise data exchange. The converter infers types and generates a matching Swift model.

What serialization library does the generated Swift code assume?

The generated code is compatible with the standard Swift serialization ecosystem — Swift structs conforming to Codable with CodingKeys where needed. No unusual dependencies required.

What version of Swift does the output target?

The converter targets modern Swift conventions — Swift structs conforming to Codable with CodingKeys where needed. If you need output for an older version, the generated code can typically be adapted with minor changes.
