Why generate Swift structs from my config?

Swift Codable structs let you deserialize config files directly using JSONDecoder. This gives you type safety for your entire configuration and catches errors at compile time.

How does the tool handle nested config sections?

Each nested object becomes a separate Swift struct. The tool produces RootApp, RootDatabase, RootDatabaseCredentials, and RootFeatures structs, each with properly typed properties and Codable conformance.

Generate Swift Structs from Config Object

Application configs have deep nesting: app settings, database credentials, feature flags. This example generates Swift Codable structs from a multi-level config structure so you can deserialize configuration files directly in your Swift application.

What You Get

The tool produces:

Root Root struct with three top-level sections: App, Database, Features
RootApp struct with Name, Version, Debug properties
RootDatabase struct with Host, Port, and Credentials nested struct
RootDatabaseCredentials struct for database auth
RootFeatures struct with DarkMode, MaxConnections, and AllowedOrigins array
Proper Swift type mappings: String, Int, Double, Bool, [String]

How to Use

The example loads with a sample application config in Swift mode
The nested structure shows how each config section gets its own struct
Copy the structs and paste them into your Swift project
Replace with your actual config JSON to generate structs for your project

Real-World Pattern

Swift config loading with Codable structs works seamlessly with JSONDecoder. Generate structs from your default config, then decode them from JSON files in your app bundle or from network responses.
