Convert XML to Swift online, free. XML is a verbose, self-describing markup format used in SOAP, RSS and enterprise systems. Swift Codable structs decode and encode JSON with compile-time safety. XML to Swift conversion parses your XML against the W3C XML 1.0 grammar (https://www.w3.org/TR/xml/), builds an in-memory model of its keys, nested objects and arrays, then emits ready-to-use Swift types following the Swift Codable conventions. Processing runs in your browser in JavaScript with no upload or server round-trip — no size limit beyond your device's memory, so multi-megabyte documents convert in milliseconds and sensitive payloads never leave your machine. Typical uses include iOS/macOS apps, Vapor services and API client models.
It maps the full structure of your XML onto idiomatic Swift types, following the Swift Codable conventions. 100% free, no registration, and complete privacy — everything runs locally in your browser, so your data never touches a server.
Paste XML and generate Swift types from Swift immediately. Conversion runs client-side, so there is no upload wait and large documents stay fast.
Nested XML objects, tables and arrays are mapped faithfully onto Swift, including nested types and optional fields.
Your XML never leaves your device — everything is processed locally in JavaScript, with nothing logged or stored.
Unlimited conversions with no account, no quotas, and no watermark. Works on desktop and mobile.
A XML document and its Swift equivalent:
XML input:
<product>
<sku>A-100</sku>
<price>19.99</price>
<active>true</active>
</product>Output:
struct Product: Codable {
let sku: String
let price: Double
let active: Bool
}Paste your XML into the editor and press "Convert to Swift". The tool parses it against the W3C XML 1.0 grammar, then generates Swift types following Swift Codable conventions — instantly and entirely in your browser. You can validate or format the XML first to be sure it is clean.
XML has no native numbers, booleans or arrays. Repeated child elements become lists in Swift, attributes and element text become fields, and values stay strings unless Swift coerces them — so review numeric or boolean fields after converting.
Optional or nullable members in the generated Swift are inferred from keys missing in some records of your XML, following Swift Codable. Include the optional fields in your sample so they are typed correctly.
XML (eXtensible Markup Language) (XML) — XML is a verbose, self-describing markup format used in SOAP, RSS and enterprise systems. Swift structs (Codable) (Swift) — Swift Codable structs decode and encode JSON with compile-time safety. This converter maps the structure of your XML onto Swift so you can use it for iOS/macOS apps.
Yes. Invalid XML is flagged with a clear error before anything is converted. Common XML problems to check are matched start and end tags, a single root element, and quoted attribute values. Starting from clean input keeps the generated Swift accurate.
Yes. The entire XML-to-Swift conversion runs locally in your browser in JavaScript — your XML is never uploaded, logged or stored. That matters when the data is something like SOAP web services, which should not leave your machine.
The generated Swift is ready for iOS/macOS apps, Vapor services and API client models. Copy or download it and drop it straight into your codebase.
