Convert YAML to Swift online, free. YAML is an indentation-based superset of JSON favoured for human-edited config. Swift Codable structs decode and encode JSON with compile-time safety. YAML to Swift conversion parses your YAML against the YAML 1.2.2 grammar (https://yaml.org/spec/1.2.2/), 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 YAML 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 YAML and generate Swift types from Swift immediately. Conversion runs client-side, so there is no upload wait and large documents stay fast.
Nested YAML objects, tables and arrays are mapped faithfully onto Swift, including nested types and optional fields.
Your YAML 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.
Example: YAML → Swift
struct User: Codable {
let name: String
let age: Int
let email: String?
}Converting YAML to Swift is simple with our free online tool. Just paste or upload your YAML data, click the "Convert to Swift" button, and get instant results. The conversion happens in your browser, ensuring privacy and speed. No registration or installation required.
Yes! Our YAML to Swift converter is completely free to use with no limitations. You can convert unlimited files, and there are no hidden fees, registration requirements, or usage restrictions. All processing happens locally in your browser for maximum privacy.
Yes, our tool can handle YAML files of various sizes. Since the conversion happens in your browser, the limit depends on your device's memory. Most modern browsers can handle files up to several megabytes without issues. For very large files, ensure you have sufficient RAM available.
Absolutely! Your data never leaves your device. All YAML to Swift conversion happens locally in your browser using JavaScript. We don't upload, store, or transmit your data to any server. This ensures complete privacy and security for sensitive information.
YAML (YAML Ain't Markup Language) (YAML) and Swift structs (Codable) (Swift) are different serialization formats, each with its own syntax and strengths. Data often needs to move between them when integrating tools, APIs, or configuration systems that expect a specific format. This converter maps the structure of your YAML onto valid Swift so you can use it wherever Swift is required.
Yes! Our YAML to Swift converter works perfectly on mobile devices (smartphones and tablets) as well as desktop computers. The responsive design ensures a smooth experience on any screen size. Just open https://tools.seagit.com/yaml-to-swift in your mobile browser.
Yes, our tool includes built-in YAML validation. If your YAML data contains syntax errors, you'll receive clear error messages indicating what needs to be fixed. This helps ensure your converted Swift output is accurate and valid.
