Modern Swift Practices

This skill provides access to exclusive technical documentation representing Apple's recommended best practices. It covers the "Liquid Glass" design system, on-device AI integration, and core framework updates found in the latest Xcode tools.

Capabilities

This skill enables you to:

• Adopt Design Standards: Implement the "Liquid Glass" design language across SwiftUI, UIKit, and AppKit consistently.
• Implement Intelligent Features: Correctly integrate on-device LLMs and visual intelligence.
• Follow Modern Patterns: Apply the latest best practices for Swift Concurrency, SwiftData, and Foundation.
• Use Modern Components: Leverage new SwiftUI capabilities like AlarmKit integration and 3D charts properly.

Instructions

1. Identify the User's Goal

   • designing a new UI -> Check Liquid Glass Design resources.
   • adding AI/ML features -> Check Intelligence & AI resources.
   • upgrading/refactoring code -> Check Core Framework Updates for best practices.

2. Locate the Resource

   • The documentation files are stored in the resources/ directory of this skill.
   • Use ls .agent/skills/apple-best-practices/resources/ to see available files if unsure.

3. Read and Apply

   • Use the view_file tool to read the specific markdown file.
   • Extract code snippets and implementation guidelines.
   • Apply them to the user's project context to ensure compliance with Apple's standards.

Examples

Example 1: Implementing Liquid Glass in SwiftUI

User: "Make this button look like the new Apple style." Action: Read SwiftUI-Implementing-Liquid-Glass-Design.md to find the correct modifiers and materials.

Example 2: Adding Local LLM Support

User: "I want to use a local model for text generation." Action: Read FoundationModels-Using-on-device-LLM-in-your-app.md to understand the recommended model loading pipeline.

Example 3: Modern Concurrency

User: "How should I structure my async code?" Action: Read Swift-Concurrency-Updates.md for the latest patterns.
