SwiftUI Best Practices Advisor-AI-powered SwiftUI code advisor

Example

The Advisor helps developers design applications following the MVVM architecture to decouple UI from business logic, enabling more modular and testable code. For instance, in a scenario where the UI layer becomes too complex with logic for data fetching or user interaction, the Advisor shows how to separate these concerns by placing data-handling logic in the ViewModel, keeping the View's role purely for rendering the UI.

Scenario

A team developing a shopping app with extensive filtering and search features uses the Advisor to ensure their code remains manageable by separating the view and data-handling logic using the MVVM pattern.

Example

The Advisor demonstrates how to integrate the Combine framework for handling asynchronous events, data streams, and reactive state updates within a SwiftUI app. For example, it can help manage real-time updates from a network service by binding these updates to UI elements using publishers.

Scenario

A developer building a stock market app that fetches live stock prices uses the Advisor to integrate Combine to ensure that the UI automatically reflects any changes in data without manual updates or unnecessary state management code.

Example

The Advisor provides strategies for optimizing the performance of SwiftUI apps by minimizing unnecessary view re-renders and controlling state propagation. For example, it advises using `@StateObject` instead of `@ObservedObject` when necessary to ensure that the object is only created once during the view's lifecycle.

Scenario

A developer notices that their app slows down when transitioning between views. The Advisor helps them refactor the app's state management using best practices (like `@EnvironmentObject` or `@StateObject`) to improve efficiency.
