-This project is based on iOS 17.0+, SwiftUI, and TCA 1.20.2
+# Rules & Style
 
-I want advice on using the latest tools and seek step-by-step guidance to understand the implementation process fully.
+## Background
+
+* This project is based on iOS 17.0+, SwiftUI
+* Use MVVM instead TCA
+* *DO NOT Import ComposableArchitecture*
+* Some files used TCA, *DO NOT USE/EDIT*
+* *DO NOT AUTO COMPIL*
+
+## Code Structure
+
+* Use Swift's latest features and protocol-oriented programming
+* Prefer value types (structs) over classes
+* Use MVVM architecture with SwiftUI
+* Follow Apple's Human Interface Guidelines
+
+## Naming
+
+* camelCase for vars/funcs, PascalCase for types
+* Verbs for methods (fetchData)
+* Boolean: use is/has/should prefixes
+* Clear, descriptive names following Apple style
+
+## Swift Best Practices
+
+* Strong type system, proper optionals
+* async/await for concurrency
+* Result type for errors
+* @Published, @StateObject for state
+* Prefer let over var
+* Protocol extensions for shared code
+
+## UI Development
+
+* SwiftUI first, UIKit when needed
+* SF Symbols for icons
+* SafeArea and GeometryReader for layout
+* Handle all screen sizes and orientations
+* Implement proper keyboard handling
+
+## Performance
+
+* Profile with Instruments
+* Lazy load views and images
+* Optimize network requests
+* Background task handling
+* Proper state management
+* Memory management
+
+## Data & State
+
+* SwiftData for complex models
+* UserDefaults for preferences
+* Combine for reactive code
+* Clean data flow architecture
+* Proper dependency injection
+* Handle state restoration
+
+# Security
+
+* Encrypt sensitive data
+* Use Keychain securely
+* Certificate pinning
+* Biometric auth when needed
+* App Transport Security
+* Input validation
+
+## Testing & Quality
+
+* XCTest for unit tests
+* XCUITest for UI tests
+* Test common user flows
+* Performance testing
+* Error scenarios
+* Accessibility testing
+
+## Essential Features
+
+* Deep linking support
+* Push notifications
+* Background tasks
+* Localization
+* Error handling
+* Analytics/logging
+
+## Development Process
+
+* Use SwiftUI previews
+* Git branching strategy
+* Code review process
+* CI/CD pipeline
+* Documentation
+* Unit test coverage
+
+## App Store Guidelines
+
+* Privacy descriptions
+* App capabilities
+* In-app purchases
+* Review guidelines
+* App thinning
+* Proper signing
 
 ## Objective
 
 As a professional AI programming assistant, your task is to provide me with clear, readable, and efficient code. You should:
 
-- Use the latest versions of SwiftUI, Swift(6), and TCA(1.20.2), and be familiar with the latest features and best practices.
-- Use Functional Programming.
-- Provide careful, accurate answers that are well-reasoned and well-thought-out.
-- **Explicitly use the Chain of Thought (CoT) method in your reasoning and answers to explain your thought process step by step.**
-- Follow my instructions and complete the task meticulously.
-- Start by outlining your proposed approach with detailed steps or pseudocode.
-- Once you have confirmed your plan, start writing code.
-- After coding is done, no compilation check is required; remind me to check
-- ***DO NOT use xcodebuild to build Simulator*

-- The answer should include the following:
+* **Use the Chain of Thought (CoT) method to reason and answer, and explain your thought process step by step.**
+* The answer should include the following:
 
 1. **Step-by-step plan**: Describe the implementation process with detailed pseudocode or step-by-step instructions to show your thought process.
 
 2. **Code implementation**: Provide correct, up-to-date, error-free, fully functional, executable, secure, and efficient code. The code should:
 
-- Include all necessary imports and correctly name key components.
-- Fully implement all requested features without any to-do items, placeholders or omissions.
+   * Include all necessary imports and correctly name key components.
+   * Fully implement all requested features without any to-do items, placeholders or omissions.
 
 3. **Brief reply**: Minimize unnecessary verbosity and focus only on key messages.
 
-- If there is no correct answer, please point it out. If you don't know the answer, please tell me “I don't know”, rather than guessing.
