SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill provides the foundational knowledge and best practices for building user interfaces across all Apple platforms using SwiftUI, ensuring consistency and efficiency.

Core Features & Use Cases

  • Cross-Platform UI: Build UIs that adapt seamlessly to iOS, macOS, iPadOS, watchOS, and visionOS.
  • Modern State Management: Implement reactive UIs with @State, @Binding, and the latest @Observable macro.
  • Declarative Navigation: Structure complex navigation flows using NavigationStack and NavigationSplitView.
  • Data Persistence: Utilize SwiftData for efficient and modern data storage.
  • Use Case: Develop a new feature for an existing iOS app that requires a complex, multi-column layout on iPad and a streamlined list view on iPhone, all while managing user preferences and data synchronization.

Quick Start

Use the swiftui-core skill to create a basic SwiftUI view with a text field and a button that updates the text.

FAQPage Schema
How do I manage state in SwiftUI using @Observable and @Binding?▼

State management in SwiftUI uses @State for local view data, @Binding to link views, and the @Observable macro for reactive models. This approach ensures UI consistency across Apple platforms when handling user preferences and data synchronization.

What's the best way to structure declarative navigation in SwiftUI?▼

Declarative navigation in SwiftUI is structured using NavigationStack for stack-based flows and NavigationSplitView for multi-column layouts. This allows you to adapt complex navigation hierarchies seamlessly across iPhone and iPad.

Can I use SwiftData for data persistence across all Apple platforms?▼

Yes, SwiftData provides modern data persistence for SwiftUI applications across all Apple platforms. It integrates natively with SwiftUI views to enable efficient data storage and reactive UI updates without complex boilerplate.

How do I adapt a SwiftUI interface for cross-platform UI on iOS, macOS, and watchOS?▼

Cross-platform UI in SwiftUI adapts to iOS, macOS, iPadOS, watchOS, and visionOS by emphasizing view composition and platform-specific adaptations. You build declarative layouts that automatically adjust to different screen sizes and input methods.

Does SwiftUI core require any external dependencies for building apps?▼

No, this SwiftUI core guidance has zero external dependencies. It relies entirely on native Apple frameworks and modern best practices for view composition, state management, and data persistence to ensure consistency and efficiency.
