SwiftUI Developer-SwiftUI Development Insights

Example

Diagnosing and resolving a common issue where a List view does not update as expected due to improper state management.

Scenario

A developer is struggling with a List in SwiftUI that fails to reflect changes when the underlying data changes. The SwiftUI Developer GPT would offer a detailed walkthrough on ensuring the data structure conforms to ObservableObject, utilizing @Published property wrappers for the properties that need monitoring, and binding the List to these observable properties correctly.

Example

Optimizing SwiftUI views for better performance by reducing unnecessary view recalculations.

Scenario

A developer faces sluggish UI performance in a complex SwiftUI app. This GPT can advise on strategies like breaking down the view hierarchy into smaller, reusable components, leveraging memoization techniques with @State and @ObservedObject, and ensuring efficient data flow to minimize view refreshes.

Example

Adopting MVVM architecture in SwiftUI applications to ensure clean separation of concerns and enhance maintainability.

Scenario

A developer is new to architectural patterns in SwiftUI. The GPT provides insights on structuring the codebase using Model-View-ViewModel (MVVM) architecture, explaining how to bind a ViewModel to a View using @ObservedObject, and demonstrating data flow between the model and the view, ensuring testability and scalability.
