SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill addresses the challenge of managing complex Swift logic and behavior directly within UI code, making it difficult to understand, maintain, and test. It promotes a cleaner architecture by externalizing this logic into dedicated, observable classes.

Core Features & Use Cases

Decouples Logic: Moves Swift logic and behavior out of UI components (SwiftUI, UIKit, AppKit) into isolated, testable classes.
Enhances Testability: Facilitates easier unit testing of business logic.
Improves Readability: Creates more organized and understandable codebases.
Use Case: Refactor a complex data fetching and processing module currently embedded in a SwiftUI view into a dedicated @Observable model class, improving its testability and reusability.

Quick Start

Use the pfw-observable-models skill to refactor the provided Swift view logic into a new observable model class.

FAQPage Schema

How do I separate Swift logic from my SwiftUI views for better testing?▼

To separate Swift logic from SwiftUI views, you extract business logic and behavior into dedicated, testable classes using the @Observable macro. This decouples functionality from UI components, making your codebase easier to understand, maintain, and unit test.

What is the best way to refactor complex data fetching logic currently embedded in a UI component?▼

The best way to refactor embedded data fetching logic is moving it into an isolated observable model class. This externalizes functionality from your UI components, supporting asynchronous operations and dependency injection within a clean, testable architecture.

Can I use the @Observable macro with asynchronous operations and dependency injection?▼

Yes, you can use the @Observable macro with asynchronous operations and dependency injection. The approach organizes Swift logic into dedicated classes that explicitly support these patterns, ensuring complex behavior remains isolated and fully testable.

Does decoupling logic into observable models work for both SwiftUI and UIKit?▼

Decoupling logic into observable models works for SwiftUI, UIKit, and AppKit. By moving behavior out of UI components into isolated classes, you achieve a cleaner separation of concerns across different platforms while improving code readability.

Why should I move business logic out of my UI components in Swift?▼

You should move business logic out of UI components because managing complex Swift behavior directly within UI code makes it difficult to understand, maintain, and test. Externalizing this logic into observable classes creates a cleaner architecture.

When should I not use observable models for Swift architecture?▼

You should avoid observable models when your UI component contains only trivial, static logic that lacks complex behavior or asynchronous operations. If there is no substantial business logic to test or decouple, introducing an isolated model class adds unnecessary architectural overhead.
