What is the main benefit of using FOSMVVM Fields?

It creates a single source of truth for form data, allowing the same validation rules and localization to be used across ViewModels, API requests, and database models.

Does this skill support multi-platform Swift projects?

Yes, it is designed for Swift libraries supporting macOS, iOS, Windows, and Linux.

Can I customize the validation rules?

Yes, the skill interprets field requirements from your conversation to generate specific constraints like length ranges, required status, and value ranges.

What files are generated by this skill?

It generates a Fields protocol for logic, a Messages struct for localization mapping, and a YAML file for the actual localized string content.

Mobile Development

Generates standardized Swift form specifications, validation rules, and localization files following the FOSMVVM pattern.

The FOSMVVM Fields Generator automates the creation of robust form contracts by generating Swift protocols, validation logic, and YAML-based localization files. By defining a single source of truth for user input fields, this skill ensures consistent validation and UI behavior across client-side ViewModels, server-side request bodies, and persistent data models. It simplifies the implementation of complex forms by handling field types, input semantics, and localized error messages, making it an essential tool for developers building multi-platform Swift applications using the FOSMVVM architecture.
