User Guide: Auto-Generating Swift Codable structures from JSON
What is JSON to Swift Codable Conversion?
iOS and macOS development (SwiftUI, UIKit) relies on the Codable protocol to parse JSON responses into native data models safely. This compiler reads JSON keys recursively, parses field definitions, and creates corresponding Swift structs complete with properties and GSON-like CodingKeys mappings.
Step-by-Step Instructions
- Enter JSON: Paste your structured response list or object map inside the input panel.
- Set Options: Customize the base Struct name and toggle camelCase auto-conversion via CodingKeys.
- Save File: The compiler builds standard Swift code. Copy or download as a `.swift` file.
Swift coding conventions & key maps
Swift code follows camelCase guidelines. If your backend returns snake_case keys (e.g. profile_details), our compiler maps them to clean camelCase variables (profileDetails) natively, keeping parsing active via the auto-generated CodingKeys enum.
