FAQPage Schema

How do I review SwiftUI code for state management and performance issues?▼

SwiftUI code review assesses state management, view composition, performance, and accessibility to provide a prioritized list of improvements. It ensures correct data flow using @Observable and @State for iOS 17+.

What is the best way to modernize legacy SwiftUI views for iOS 17?▼

Modernizing legacy SwiftUI views involves guided refactoring to align with Apple Human Interface Guidelines. This extracts views and migrates data flow to modern patterns like @Observable for scalable maintainability.

How does @Observable work for state management in SwiftUI?▼

@Observable manages state in iOS 17+ by replacing ObservableObject, allowing SwiftUI to track property changes efficiently. Expert review verifies correct data flow and safe API usage when migrating to this pattern.

Can I use this to audit SwiftUI accessibility and macOS-specific APIs?▼

Yes, SwiftUI code review scope includes auditing accessibility and macOS-specific APIs. It assesses view composition and ensures adherence to Apple Human Interface Guidelines and robust error handling across Apple platforms.

When should I not use @State for data flow in SwiftUI?▼

You should not use @State for complex data flow across multiple views, as it manages local state only. Expert review identifies these limitations and guides migration to scalable patterns like @Observable.

How do I prepare SwiftUI views for Liquid Glass on iOS 26+?▼

Preparing SwiftUI views for Liquid Glass on iOS 26+ involves readiness checks during code review. This verifies view composition and modern patterns safely support the new framework features when explicitly requested.
