swiftui general rules

When reviewing or writing code, apply these guidelines:

• You are an expert in coding with Swift and SwiftUI.
• Always write maintainable and clean code.
• Focus on the latest August, September 2024 version of the documentation and features.
• Descriptions should be short and concise.
• Don't remove any comments.

swiftui project structure rules

When reviewing or writing code, apply these guidelines:

• Enforce the following SwiftUI project structure:
  • The main folder contains a "Sources" folder with:
    • "App" for main files
    • "Views" divided into "Home" and "Profile" sections with their ViewModels
    • "Shared" for reusable components and modifiers
  • "Models" for data models
  • "ViewModels" for view-specific logic
  • "Services" with:
    • "Network" for networking
    • "Persistence" for data storage
  • "Utilities" for extensions, constants, and helpers
  • The "Resources" folder holds:
    • "Assets" for images and colors
    • "Localization" for localized strings
    • "Fonts" for custom fonts
  • The "Tests" folder includes:
    • "UnitTests" for unit testing
    • "UITests" for UI testing

swiftui ui design rules

When reviewing or writing code, apply these guidelines:

• Use Built-in Components: Utilize SwiftUI's native UI elements like List, NavigationView, TabView, and SF Symbols for a polished, iOS-consistent look.
• Master Layout Tools: Employ VStack, HStack, ZStack, Spacer, and Padding for responsive designs; use LazyVGrid and LazyHGrid for grids; GeometryReader for dynamic layouts.
• Add Visual Flair: Enhance UIs with shadows, gradients, blurs, custom shapes, and animations using the .animation() modifier for smooth transitions.
• Design for Interaction: Incorporate gestures (swipes, long presses), haptic feedback, clear navigation, and responsive elements to improve user engagement and satisfaction.

Iron Laws

1. ALWAYS use @MainActor for UI updates — SwiftUI and UIKit views must be modified on the main thread; background thread UI updates cause runtime crashes or silent visual corruption.
2. NEVER use @State for data that is shared between views — @State is local to the view and does not propagate changes to siblings or parents; use @ObservedObject, @EnvironmentObject, or @StateObject for shared model data.
3. ALWAYS implement proper memory management with [weak self] in closures that capture self — strong self capture in closures that are held by the captured object creates retain cycles and memory leaks.
4. NEVER perform network or disk I/O on the main thread — synchronous I/O on the main thread blocks the run loop, causes UI freezes, and triggers watchdog terminations.
