Q: How to parse optional fields in Argo?

Use the `<|?` operator for optional values, like `json <|? "email"`, which returns an optional type and handles missing keys or null values gracefully, as demonstrated in the README example.

Q: Argo vs Swift Codable: which is better for JSON parsing?

Argo offers more explicit error handling and a functional approach with operators, while Codable is built-in and dependency-free. Choose Argo if you need fine-grained control; otherwise, Codable is often sufficient for standard use cases.

Q: How to handle nested JSON objects with Argo?

Use key path syntax in the decode method, such as `json <| ["nested", "key"]`, to access deeply nested values directly without manual traversal, as shown in the company name parsing example.

Q: Argo installation issues with CocoaPods?

Ensure you're using CocoaPods 0.36+ and have `use_frameworks!` in your Podfile. For newer Argo versions, you may need to link both Argo and Runes frameworks, as specified in the installation instructions.

Q: How to decode custom enums in Argo?

Make your enum conform to Decodable and implement the static decode method using Argo's operators, similar to structs. You can pattern match on JSON values to map to enum cases, ensuring type safety.

Q: Argo error handling examples?

Argo returns a `Decoded ` type that can be .success or .failure. Use switch statements or higher-order functions like `map` to extract values or handle errors, providing detailed feedback on parsing failures from the JSON structure.
