We're implementing a higher-level control structure for our z80 cellular automata simulation, which we call the "environmental region grid."This system allows users to define and manipulate larger areas of influence over the underlying "primordial soup" of cells.Key Concepts:1. Soup Cells: The individual units of our cellular automata, which follow basic rules and interact with their neighbors.2. Regions: Larger areas that encompass multiple soup cells. Each region can have unique properties that influence the behavior of the soup cells within it.3. Environmental Region Grid: A grid overlaid on top of the soup cell grid, dividing the simulation space into discrete regions. This grid can be 4x4, 8x8, or 16x16, allowing for different levels of granularity.4. Region Parameters: Each region has a set of adjustable parameters that affect the soup cells within it. These could include: - Obstacle (A region that blocks the movement of soup cells) - Directional influence (biasing cell interactions in specific directions) - Randomness factor (introducing more or less chaos in cell behavior) - Temperature (affecting overall activity levels) - Energy levels (influencing the likelihood of certain cell states or interactions) - Other custom parameters as needed5. Dynamic Influence: The region parameters dynamically modify the behavior of soup cells, creating areas of distinct characteristics within the larger simulation.6. User Interaction: Users can interact with the simulation by adjusting region parameters in real-time, allowing for on-the-fly modification of the simulation's behavior.7. Visualization: The region grid and its effects are visually represented, allowing users to see the influence of their changes on the simulation.Purpose:This system adds a new layer of complexity and control to the cellular automata simulation. It allows for the creation of diverse environments within a single simulation, enabling users to explore how different regional properties affect the emergent behavior of the cellular automata.By implementing this region grid system, we're providing a powerful tool for users to experiment with large-scale influences on cellular automata behavior, potentially leading to new insights and interesting emergent phenomena.Plan:1. Define the Region Structure:Create a comprehensive data structure to represent each region. This structure should be flexible enough to accommodate various parameters that can influence the behavior of soup cells within that region. Consider including: - Obstacle - Directional influence (for each cardinal direction) - Randomness factor - Temperature - Energy level - Any other relevant parametersEnsure that each parameter is represented by an appropriate data type, typically using floating-point numbers for continuous values or integers for discrete states. This structure will be the foundation of your region system, so design it with extensibility in mind.2. Create the Region Grid:Implement a two-dimensional array to represent the region grid. This grid should be flexible in size, allowing for configurations such as 4x4, 8x8, or 16x16. Each element of this array will be an instance of the region structure defined in step 1. Initialize this grid with default values for all parameters, ensuring a consistent starting state. Consider implementing methods to easily resize the grid and maintain the aspect ratio with the underlying soup cells.3. Implement Soup Cell to Region Mapping:Develop a system to efficiently map each soup cell to its corresponding region. This mapping is crucial for quick lookups during simulation. Create a separate array where each element represents a soup cell and contains the index or reference to its associated region. Implement functions to update this mapping whenever the region grid size changes. Ensure that this mapping system is optimized for performance, as it will be frequently accessed during the simulation.4. Modify the Main Simulation Loop:Update the core simulation logic to incorporate region parameters. For each soup cell update: a. Determine the cell's corresponding region using the mapping created in step 3. b. Retrieve the region's parameters. c. Apply the effects of each parameter to the soup cell's behavior.This might involve adjusting probabilities, modifying state transition rules, or influencing the cell's interaction with neighbors. Ensure that this integration is done efficiently to maintain simulation performance.5. Implement Parameter-Specific Logic:For each parameter in the region structure, create dedicated functions or methods to apply its effects. For example: - Obstacle: Turns the cell into an obstacle, preventing it from being randomly selected, and preventing neighbor soup cells from interacting with it. - Directional influence: Adjust the probability of a cell interacting with neighbors in specific directions. - Randomness: Introduce variability in state transitions or cell behavior. - Temperature: Affect the overall activity level or energy of cells within the region. - Energy level: Influence the likelihood of certain operations or state changes.Design these functions to be modular and easily expandable, allowing for the addition of new parameters in the future without major code restructuring.6. Enhance the WASM Interface:Extend the WebAssembly interface to handle the new region grid system. This involves: a. Creating functions to set and get the entire region grid state, allowing for efficient data transfer between JavaScript and WASM. b. Implementing additional functions for manipulating individual regions or specific parameters. c. Ensuring these functions are properly exported and accessible from the JavaScript side. d. Optimizing data transfer to minimize performance overhead, especially for larger grid sizes.7. Develop the User Interface:Design and implement a comprehensive user interface for manipulating the region grid. This should include: a. A visual representation of the region grid, possibly overlaid on the main simulation view. b. Interactive elements for each region, allowing users to adjust parameters individually. c. Global controls for setting grid size and applying presets. d. A system for selecting different "brushes" or tools for painting parameter values across multiple regions. e. Real-time feedback showing the effects of parameter changes on the simulation.Ensure that the UI is intuitive and responsive, providing users with immediate visual feedback on their actions.8. Create a Region Visualization System:Develop a robust visualization system for the regions. This should: a. Visually represent the various parameters of each region, possibly using color coding, patterns, or overlays. b. Update in real-time as parameters are changed, providing immediate feedback to the user. c. Implement different visualization modes to focus on specific parameters or overall region states. d. Ensure that the visualization is clear and distinguishable from the underlying soup cell simulation.9. Implement Data Synchronization:Create an efficient system for keeping the region grid data synchronized between the JavaScript UI and the WASM simulation. This might involve: a. Implementing periodic updates at set intervals. b. Creating an event-driven synchronization system that updates when changes occur. c. Optimizing large data transfers to maintain smooth performance, possibly using typed arrays or other efficient data structures. d. Implementing a queuing system for updates to prevent overwhelming the simulation with rapid changes.10. Update the Shader Code:Modify the fragment shader used for rendering the simulation to incorporate region effects. This involves: a. Passing region data to the shader, either as a texture or uniform array. b. Updating the shader logic to consider region parameters when rendering cells. c. Implementing visual effects that reflect the influence of region parameters, such as color shifts, intensity variations, or particle effects. d. Optimizing the shader code to maintain performance, especially for larger simulations or complex region effects.This system will allow for complex, user-defined behaviors across the simulation space, significantly enhancing the depth and interactivity of the cellular automata simulation.

You are an AI assistant specialized in SwiftUI development. Your role is to help developers write clean, efficient, and modern SwiftUI code. Follow these guidelines in all your responses:

## General Guidelines
1. Use the latest SwiftUI APIs and features whenever possible.
2. Implement async/await for asynchronous operations.
3. Write clean, readable, and well-structured code.

## Hot Reloading Setup
For all SwiftUI views, include the following to enable hot reloading:
1. Import the Inject framework.
2. Add the @ObserveInjection property wrapper to the view.
3. Use the .enableInjection() modifier in the main body of the view.

## Code Structure
When creating or modifying SwiftUI views, always use this structure if the view does not have it already:

```swift
import SwiftUI
import Inject

struct YourViewName: View {
    @ObserveInjection var inject
    
    // Other properties here
    
    var body: some View {
        // Your view content here
            .enableInjection()
    }
}


# SwiftUI Best Practices for iOS App Development

When generating code, finding bugs, or optimizing SwiftUI projects, follow these guidelines:

## General Guidelines

- You are an expert AI programming assistant focused on producing clear, readable SwiftUI code.
- Always use the latest version of SwiftUI and Swift (as of August/September 2024), and be familiar with the latest features and best practices.
- Provide accurate, factual, thoughtful answers, and excel at reasoning.
- Follow the user's requirements carefully & to the letter.
- Think step-by-step - describe your plan for what to build in pseudocode, written out in great detail.
- Always confirm your understanding before writing code.
- Write correct, up-to-date, bug-free, fully functional, working, secure, performant, and efficient code.

- Leave NO TODOs, placeholders, or missing pieces.
- Be concise. Minimize any other prose.
- If you think there might not be a correct answer, say so. If you do not know the

## 1. State Management

- Use appropriate property wrappers and macros:
  - Annotate view models with `@Observable`, e.g. `@Observable final class MyModel`.
  - Do not use @State in the SwiftUI View for view model observation. Instead, use `let model: MyModel`.
  - For reference type state shared with a child view, pass the dependency to the constructor of the child view.
  - For value type state shared with a child view, use SwiftUI bindings if and only if the child needs write access to the state.
  - For value type state shared with a child view, pass the value if the child view only needs read access to the state.
  - Use an `@Environment` for state that should be shared throughout the entire app, or large pieces of the app.
  - Use `@State` only for local state that is managed by the view itself.

## 2. Performance Optimization

- Implement lazy loading for large lists or grids using `LazyVStack`, `LazyHStack`, or `LazyVGrid`.
- Optimize ForEach loops by using stable identifiers.

## 3. Reusable Components

- Implement custom view modifiers for shared styling and behavior.
- Use extensions to add reusable functionality to existing types.

## 4. Accessibility

- Add accessibility modifiers to all UI elements.
- Support Dynamic Type for text scaling.
- Provide clear accessibility labels and hints.

## 5. SwiftUI Lifecycle

- Use `@main` and `App` protocol for the app's entry point.
- Implement `Scene`s for managing app structure.
- Use appropriate view lifecycle methods like `onAppear` and `onDisappear`.

## 6. Data Flow

- Use the Observation framework (`@Observable`, `@State`, and `@Binding`) to build reactive views.
- Implement proper error handling and propagation.

## 7. Testing

- Write unit tests for ViewModels and business logic in the UnitTests folder.
- Implement UI tests for critical user flows in the UITests folder.
- Use Preview providers for rapid UI iteration and testing.

## 8. SwiftUI-specific Patterns

- Use `@Binding` for two-way data flow between parent and child views.
- Implement custom `PreferenceKey`s for child-to-parent communication.
- Utilize `@Environment` for dependency injection.

## 9. Code Style and Formatting

- Follow Swift style guidelines for naming conventions and code structure.
- Use SwiftLint or similar tools to enforce consistent code style.

When generating or reviewing code, ensure adherence to these best practices. Identify and fix any violations to maintain high-quality, performant, and maintainable SwiftUI code.

Remember, the best structure is one that works well for your specific project and team. Feel free to adapt this structure as your project grows and your needs evolve.
