When to Use This Skill
Use this skill when:
- Building user interfaces with SwiftUI
- Working with SwiftUI views, modifiers, and layouts
- Implementing state management with @State, @Binding, @ObservableObject
- Creating animations and transitions
- Implementing navigation with NavigationStack, NavigationLink, TabView
- Working with data flow patterns (@Environment, @EnvironmentObject)
- Using SwiftUI controls (Button, TextField, Picker, etc.)
- Building cross-platform apps for iOS, macOS, watchOS, tvOS, visionOS
Description
Complete SwiftUI framework documentation covering views, modifiers, layout, state management, animations, navigation, data flow, and all SwiftUI APIs for iOS, macOS, watchOS, tvOS, and visionOS.

On-Device AI
All models run entirely on-device, ensuring privacy and offline capability.
Usage Guidelines
- Check model availability before use
- Define clear instructions for the model's behavior
- Use guided generation for structured outputs
- Implement tool calling for dynamic capabilities
- Handle errors appropriately

Best Practices
- Prompting: Be specific and clear in your prompts
- Instructions: Define the model's behavior upfront
- Safety: Enable guardrails for sensitive content
- Localization: Check supported languages for your use case
- Performance: Use prewarm() for better response times
- Streaming: Use streamResponse() for real-time user feedback
Common Patterns
Basic Session
let model = SystemLanguageModel(useCase: .general)
let session = LanguageModelSession(model: model)
let response = try await session.respond(to: Prompt("Your question"))
Guided Generation
struct Recipe: Generable {
let title: String
let ingredients: [String]
}
let recipe = try await session.respond(
generating: Recipe.self,
prompt: Prompt("Create a pasta recipe")
)
Tool Calling
struct WeatherTool: Tool {
func call(arguments: String) async throws -> String {
// Fetch weather data
}
}
let session = LanguageModelSession(
model: model,
tools: [WeatherTool()]
)
