Cross-Platform App Development Skill

This skill focuses on building applications that work seamlessly across Apple's ecosystem: iOS, iPadOS, macOS, watchOS, and tvOS. It emphasizes adaptive design, platform-specific optimizations, and shared codebases using SwiftUI.

Best Practices

1. Unified Codebase: Use SwiftUI for maximum code sharing across platforms.

2. Adaptive Layouts: Design interfaces that adapt to different screen sizes and orientations.

3. Platform-Specific Features: Leverage unique capabilities of each platform while maintaining consistency.

4. Environment Awareness: Use environment values to detect platform, size classes, and capabilities.

5. Progressive Enhancement: Start with core functionality and add platform-specific features.

6. Testing Across Platforms: Regularly test on all target platforms.
