Test 1: Write a Swift function that solves the FizzBuzz problem.

Source: test1.txt

Prompt:

Write a Swift function that solves the FizzBuzz problem.

The function must have the exact signature:
`func generateFizzBuzz(upTo max: Int) -> [String]`

It must not print directly to the console. Instead, it should return an array of strings.

Rules:
1. For numbers divisible by 3, the string should be "Fizz".
2. For numbers divisible by 5, the string should be "Buzz".
3. For numbers divisible by both 3 and 5, the string should be "FizzBuzz".
4. Otherwise, it should be the number itself as a string.

Include a complete documentation comment (`///`) explaining what the function does, its parameters, and what it returns.

Response:

/// Generates an array of strings representing the FizzBuzz sequence up to a given number.
///
/// The FizzBuzz sequence follows these rules:
/// - For numbers divisible by 3, returns "Fizz"
/// - For numbers divisible by 5, returns "Buzz"
/// - For numbers divisible by both 3 and 5, returns "FizzBuzz"
/// - For all other numbers, returns the number as a string
///
/// - Parameter max: The upper limit (inclusive) for generating the FizzBuzz sequence
/// - Returns: An array of strings representing the FizzBuzz sequence from 1 to max (inclusive)
///
/// - Example:
///   ```
///   generateFizzBuzz(upTo: 5) // Returns ["1", "2", "Fizz", "4", "Buzz"]
///   generateFizzBuzz(upTo: 15) // Returns ["1", "2", "Fizz", "4", "Buzz", "Fizz", "7", "8", "Fizz", "Buzz", "11", "Fizz", "13", "14", "FizzBuzz"]
///   ```
func generateFizzBuzz(upTo max: Int) -> [String] {
    var result: [String] = []
    
    for number in 1...max {
        switch (number % 3 == 0, number % 5 == 0) {
        case (true, true):
            result.append("FizzBuzz")
        case (true, false):
            result.append("Fizz")
        case (false, true):
            result.append("Buzz")
        default:
            result.append(String(number))
        }
    }
    
    return result
}

Test 2: Create a complete SwiftUI view for a user profile card.

Source: test2.txt

Prompt:

Create a complete SwiftUI view for a user profile card.

The view should be named `UserProfileCard` and be initialized with a simple `User` struct containing `name: String`, `handle: String`, and `avatarURL: URL`.

Requirements:
- Use an `AsyncImage` to load the user's avatar from the URL.
- Display the user's name in a `.headline` font and their handle (e.g., "@username") in a `.subheadline` font with a secondary color.
- Include a "Follow" button that uses the "person.badge.plus" SF Symbol.
- Arrange the elements cleanly inside an HStack with appropriate spacing.
- The entire card should have a subtle shadow and rounded corners.

Response:

import SwiftUI

// User struct definition
struct User: Identifiable {
    let id = UUID()
    let name: String
    let handle: String
    let avatarURL: URL
}

// User profile card view
struct UserProfileCard: View {
    let user: User
    
    var body: some View {
        HStack(spacing: 16) {
            AsyncImage(url: user.avatarURL) { image in
                image
                    .resizable()
                    .aspectRatio(contentMode: .fill)
            } placeholder: {
                Rectangle()
                    .fill(Color.gray.opacity(0.3))
            }
            .frame(width: 60, height: 60)
            .clipShape(Circle())
            
            VStack(alignment: .leading, spacing: 4) {
                Text(user.name)
                    .font(.headline)
                
                Text(user.handle)
                    .font(.subheadline)
                    .foregroundColor(.secondary)
            }
            
            Spacer()
            
            Button(action: {
                // Follow action would go here
                print("Follow button tapped for \(user.name)")
            }) {
                Image(systemName: "person.badge.plus")
                    .font(.title2)
                    .foregroundColor(.blue)
                    .padding(8)
                    .background(Color(.systemBlue).opacity(0.1))
                    .clipShape(Circle())
            }
            .buttonStyle(PlainButtonStyle())
        }
        .padding(16)
        .background(Color(.systemBackground))
        .cornerRadius(12)
        .shadow(radius: 4)
        .padding(.horizontal)
    }
}

// Preview provider
struct UserProfileCard_Previews: PreviewProvider {
    static let sampleUser = User(
        name: "John Doe",
        handle: "@johndoe",
        avatarURL: URL(string: "https://via.placeholder.com/100")!
    )
    
    static var previews: some View {
        UserProfileCard(user: sampleUser)
            .previewLayout(.sizeThatFits)
            .padding()
    }
}

This SwiftUI view includes:

1. A User struct with the required properties
2. An AsyncImage that loads the avatar from the provided URL
3. The user's name displayed in .headline font
4. The handle displayed in .subheadline font with secondary color
5. A "Follow" button using the "person.badge.plus" SF Symbol
6. Clean HStack arrangement with appropriate spacing
7. Subtle shadow and rounded corners using .shadow() and .cornerRadius()
8. A preview provider for easy testing

The card has:

• Circular avatar with proper sizing
• Clean typography hierarchy
• Accessible button with visual feedback
• Subtle shadow for depth
• Rounded corners
• Proper spacing and alignment
• Placeholder for the follow action

The view is fully self-contained and can be used anywhere in a SwiftUI project by passing a User instance to the initializer.

Test 3: I have this old networking code that uses a completion handler. Please refactor it to use modern Swift Concurrency with async/await.

Source: test3.txt

Prompt:

I have this old networking code that uses a completion handler. Please refactor it to use modern Swift Concurrency with async/await.

The new function should be marked with `async throws` and return a `[Post]` object upon success. Also, include an example of how to call this new async function inside a `Task` with a `do-catch` block.

**Old Code:**
struct Post: Codable {
    let id: Int
    let title: String
}

func fetchPosts(completion: @escaping (Result<[Post], Error>) -> Void) {
    guard let url = URL(string: "https://api.example.com/posts") else { return }
    URLSession.shared.dataTask(with: url) { data, _, error in
        if let error = error { completion(.failure(error)); return }
        guard let data = data else { return }
        do {
            let posts = try JSONDecoder().decode([Post].self, from: data)
            completion(.success(posts))
        } catch {
            completion(.failure(error))
        }
    }.resume()
}

Response:

Here's the refactored code using modern Swift Concurrency with async/await:

import Foundation

struct Post: Codable {
    let id: Int
    let title: String
}

// Modern async/await version
func fetchPosts() async throws -> [Post] {
    guard let url = URL(string: "https://api.example.com/posts") else {
        throw URLError(.badURL)
    }
    
    let (data, response) = try await URLSession.shared.data(from: url)
    
    // Optional: Validate HTTP response
    if let httpResponse = response as? HTTPURLResponse,
       !(200...299).contains(httpResponse.statusCode) {
        throw URLError(.badServerResponse)
    }
    
    return try JSONDecoder().decode([Post].self, from: data)
}

// Example of how to call the async function inside a Task
func exampleUsage() {
    Task {
        do {
            let posts = try await fetchPosts()
            print("Successfully fetched \(posts.count) posts")
            // Process your posts here
            for post in posts {
                print("Post: \(post.title)")
            }
        } catch {
            print("Failed to fetch posts: \(error)")
            // Handle the error appropriately
        }
    }
}

// Alternative example with explicit error handling
func exampleUsageWithExplicitErrorHandling() {
    Task {
        do {
            let posts = try await fetchPosts()
            // Handle success
            print("Got \(posts.count) posts")
        } catch let urLError as URLError {
            switch urLError.code {
            case .notConnectedToInternet:
                print("No internet connection")
            case .timedOut:
                print("Request timed out")
            default:
                print("Network error: \(urLError)")
            }
        } catch {
            print("Unknown error: \(error)")
        }
    }
}

Key changes made:

1. Removed completion handler: The function now uses async throws instead of callback-based approach
2. Simplified error handling: Using try await with URLSession.shared.data(from:) which throws on failure
3. Added HTTP response validation: Optional but recommended to check for proper HTTP status codes
4. Cleaner return: Directly returns [Post] array on success
5. Proper error types: Uses URLError for network-related errors

Usage notes:

• The function can be called directly with try await inside an async context
• When calling from a non-async context (like in a button action), wrap it in a Task as shown in the examples
• Error handling is more straightforward with do-catch blocks
• The function now properly propagates errors through Swift's throwing mechanism

Important: Make sure your target deployment is iOS 13.0+, macOS 10.15+, or later, as async/await requires these minimum versions.

Test 4: Create a complete SwiftData example for a macOS 26 app.

Source: test4.txt

Prompt:

Create a complete SwiftData example for a macOS 26 app.

You must define two models: `Author` and `Book`. An `Author` can have many `Book`s (a one-to-many relationship).

Then, create a SwiftUI view that displays a list of all authors. When an author's name is tapped, it should navigate to a detail view that shows a list of all the books written by that specific author. Use a SwiftData `@Query` to fetch the data.

Response:

Here's a complete SwiftData example for a macOS app with Author and Book models:

// Author.swift
import SwiftData
import Foundation

@Model
final class Author {
    var name: String
    var birthYear: Int?
    @Relationship(deleteRule: .cascade, inverse: \Book.author)
    var books: [Book]
    
    init(name: String, birthYear: Int? = nil) {
        self.name = name
        self.birthYear = birthYear
        self.books = []
    }
}

// Book.swift
import SwiftData
import Foundation

@Model
final class Book {
    var title: String
    var publicationYear: Int?
    var isbn: String?
    @Relationship(inverse: \Author.books)
    var author: Author?
    
    init(title: String, publicationYear: Int? = nil, isbn: String? = nil) {
        self.title = title
        self.publicationYear = publicationYear
        self.isbn = isbn
    }
}

// AuthorListView.swift

            AuthorListView()
                .modelContainer(sharedModelContainer)
        }
    }
}

This example includes:

1. Models:

   • Author: Has a name, birth year, and a to-many relationship with books
   • Book: Has title, publication year, ISBN, and a to-one relationship with author

2. Core Features:

   • One-to-many relationship between Author and Book
   • SwiftData @Query for fetching data
   • Navigation between author list → author detail → book list
   • Add author and add book functionality
   • Proper data binding and model context handling

3. Views:

   • AuthorListView: Shows all authors with basic info
   • BookListView: Shows books for a specific author
   • AddAuthorView: Form to add new authors
   • AddBookView: Form to add books to an author

4. Key SwiftData Features:

   • @Relationship with proper delete rules
   • @Query for data fetching
   • @Environment(\.modelContext) for data persistence
   • @Predicate for filtering queries
   • Proper model container setup

To use this in your macOS app:

1. Create a new macOS SwiftData project
2. Add these files to your project
3. Make sure your app's SceneDelegate or App file includes the ModelContainer setup
4. The app will automatically create and manage the database

The app allows you to:

• View all authors in a list
• Tap on an author to see their books
• Add new authors
• Add books to existing authors
• See basic information about each author and their books

The relationships are properly configured with cascade deletion rules, so when an author is deleted, their books are also deleted.

Test 5: Write a thread-safe counter class in Swift using an actor.

Source: test5.txt

Prompt:

Write a thread-safe counter class in Swift using an `actor`.

The actor should be named `SafeCounter`. It must have a private property to hold the current count and two public methods:
1. `func increment() async`
2. `func getCount() async -> Int`

Also, provide a simple example of how to create an instance of the actor and call its methods concurrently from two different `Task`s.

Response:

Here's a thread-safe counter class in Swift using an actor:

actor SafeCounter {
    private var count: Int = 0
    
    func increment() async {
        count += 1
    }
    
    func getCount() async -> Int {
        return count
    }
}

// Example usage
func demonstrateSafeCounter() async {
    // Create an instance of the SafeCounter actor
    let counter = SafeCounter()
    
    // Create two concurrent tasks that increment the counter
    let task1 = Task {
        for _ in 0..<1000 {
            await counter.increment()
        }
    }
    
    let task2 = Task {
        for _ in 0..<1000 {
            await counter.increment()
        }
    }
    
    // Wait for both tasks to complete
    await task1.value
    await task2.value
    
    // Get the final count
    let finalCount = await counter.getCount()
    print("Final count: \(finalCount)") // Should print 2000
    
    // Example of concurrent access to get count
    let task3 = Task {
        await counter.increment()
        let count1 = await counter.getCount()
        print("Count after increment: \(count1)")
    }
    
    let task4 = Task {
        await counter.increment()
        let count2 = await counter.getCount()
        print("Count after another increment: \(count2)")
    }
    
    await task3.value
    await task4.value
}

// Run the example
Task {
    await demonstrateSafeCounter()
}

Key features of this implementation:

1. Actor Declaration: The SafeCounter actor ensures thread safety by serializing all access to its properties and methods.

2. Private Property: The count property is private, so it can only be accessed within the actor's context.

3. Async Methods: Both increment() and getCount() are async methods that can be called from other tasks.

4. Thread Safety: Since actors are inherently thread-safe, concurrent access to the counter from multiple tasks is safe without additional synchronization mechanisms.

5. Usage Example: The example demonstrates:

   • Creating multiple concurrent tasks that increment the counter
   • Using await to call actor methods
   • Ensuring proper synchronization with the actor's serialized execution model

The actor automatically handles the serialization of method calls, so even when multiple tasks call increment() or getCount() concurrently, the operations are executed one at a time in the order they were received, making the counter completely thread-safe.

Test 6: Create the code for a simple, non-configurable watchOS 26 complication that displays the current date in the .accessoryRectangular family.

Source: test6.txt

Prompt:

Create the code for a simple, non-configurable watchOS 26 complication that displays the current date in the `.accessoryRectangular` family.

The code must include:
1. A `TimelineProvider` to generate the timeline entries.
2. A `TimelineEntry` struct.
3. The main `Widget` struct.
4. A SwiftUI view for the complication's appearance.

Ensure the code correctly uses the modern WidgetKit framework.

Response:

Here's a complete implementation of a watchOS 26 complication that displays the current date in the .accessoryRectangular family:

import WidgetKit
import SwiftUI

// MARK: - Timeline Entry
struct DateComplicationEntry: TimelineEntry {
    let date: Date
    let dateString: String
    
    init(date: Date) {
        self.date = date
        self.dateString = Self.formatDate(date)
    }
    
    private static func formatDate(_ date: Date) -> String {
        let formatter = DateFormatter()
        formatter.dateStyle = .medium
        return formatter.string(from: date)
    }
}

// MARK: - Timeline Provider
struct DateComplicationProvider: TimelineProvider {
    func placeholder(in context: Context) -> DateComplicationEntry {
        DateComplicationEntry(date: Date())
    }
    
    func getSnapshot(in context: Context, completion: @escaping (DateComplicationEntry) -> ()) {
        let entry = DateComplicationEntry(date: Date())
        completion(entry)
    }
    
    func getTimeline(in context: Context, completion: @escaping (Timeline<DateComplicationEntry>) -> ()) {
        let currentDate = Date()
        let nextUpdate = Calendar.current.date(byAdding: .minute, value: 1, to: currentDate)!
        
        let entry = DateComplicationEntry(date: currentDate)
        let timeline = Timeline(entries: [entry], policy: .after(nextUpdate))
        
        completion(timeline)
    }
}

// MARK: - Widget
struct DateComplicationWidget: Widget {
    let provider = DateComplicationProvider()
    
    var body: some WidgetConfiguration {
        StaticConfiguration(
            kind: "DateComplicationWidget",
            provider: provider
        ) { entry in
            DateComplicationView(entry: entry)
        }
        .configurationDisplayName("Date Complication")
        .description("Displays the current date")
        .supportedFamilies([.accessoryRectangular])
    }
}

// MARK: - View
struct DateComplicationView: View {
    let entry: DateComplicationEntry
    
    var body: some View {
        VStack(spacing: 4) {
            Text(entry.dateString)
                .font(.system(size: 14, weight: .medium, design: .monospaced))
                .foregroundColor(.white)
                .lineLimit(1)
                .truncationMode(.tail)
        }
        .padding(.horizontal, 8)
        .padding(.vertical, 4)
        .frame(maxWidth: .infinity, maxHeight: .infinity)
        .background(Color.black)
    }
}

// MARK: - Preview
struct DateComplicationWidget_Previews: PreviewProvider {
    static var previews: some View {
        DateComplicationView(entry: DateComplicationEntry(date: Date()))
            .previewContext(WidgetPreviewContext(family: .accessoryRectangular))
    }
}

This implementation includes:

1. TimelineEntry (DateComplicationEntry):

   • Stores the current date and a formatted date string
   • Includes a static method to format the date using DateFormatter

2. TimelineProvider (DateComplicationProvider):

   • Implements all required methods: placeholder, getSnapshot, and getTimeline
   • Updates every minute to ensure the date stays current
   • Uses .after policy to schedule the next update

3. Widget (DateComplicationWidget):

   • Configured for the .accessoryRectangular family
   • Uses StaticConfiguration since it's a simple, non-configurable complication
   • Includes proper configuration metadata

4. SwiftUI View (DateComplicationView):

   • Displays the formatted date in a clean, monospaced font
   • Uses a black background to match watchOS conventions
   • Properly sized for the rectangular accessory family
   • Handles text truncation for long dates

The complication will automatically update every minute and display the current date in a compact, readable format suitable for the watchOS accessory rectangular display.

Test 7: Refactor this SwiftUI view and its ObservableObject to use the modern @Observable macro introduced in Swift 5.9. The refactored code should be simpler and should not use the @Published property wrapper or the ObservableObject protocol.

Source: test7.txt

Prompt:

Refactor this SwiftUI view and its `ObservableObject` to use the modern `@Observable` macro introduced in Swift 5.9. The refactored code should be simpler and should not use the `@Published` property wrapper or the `ObservableObject` protocol.

**Old Code:**
class UserSettings: ObservableObject {
    @Published var score: Int = 0
    @Published var username: String = "Guest"
}

struct SettingsView: View {
    @StateObject private var settings = UserSettings()
    var body: some View {
        Form {
            TextField("Username", text: $settings.username)
            Stepper("Score: \(settings.score)", value: $settings.score)
        }
    }
}

Response:

Here's the refactored code using the modern @Observable macro:

import SwiftUI

@Observable
class UserSettings {
    var score: Int = 0
    var username: String = "Guest"
}

struct SettingsView: View {
    @State private var settings = UserSettings()
    
    var body: some View {
        Form {
            TextField("Username", text: $settings.username)
            Stepper("Score: \(settings.score)", value: $settings.score)
        }
    }
}

Key changes made:

1. Removed @Published - Properties are now directly declared without the @Published wrapper
2. Removed ObservableObject protocol - No longer needed with @Observable
3. Simplified @StateObject to @State - Since we're using @Observable instead of @Published, we can use @State directly
4. Cleaner class declaration - Just the @Observable macro and regular property declarations

The @Observable macro automatically handles the observation mechanism, making the code much simpler and more concise while maintaining the same functionality. The view will automatically update when any observed properties change, just like with the previous @Published approach.

Create the code for a simple, configurable WidgetKit widget for iOS 26. The widget should display a single "Note" string. The configuration logic must use the modern App Intents framework, allowing the user to edit the note's text directly from the widget's configuration screen. Do not use the old `INIntent` based system.

Response:

Here's a complete implementation of a configurable WidgetKit widget using the modern App Intents framework for iOS 26:

// MARK: - Widget Entry
import WidgetKit
import SwiftUI

struct NoteWidgetEntry: TimelineEntry {
    let date: Date
    let note: String
}

// MARK: - Widget Provider
struct NoteWidgetProvider: AppIntentTimelineProvider {
    func placeholder(in context: Context) -> NoteWidgetEntry {
        NoteWidgetEntry(date: Date(), note: "Sample Note")
    }

    func snapshot(for configuration: NoteWidgetConfigurationIntent, in context: Context) async -> NoteWidgetEntry {
        NoteWidgetEntry(date: Date(), note: configuration.note ?? "Default Note")
    }

    func timeline(for configuration: NoteWidgetConfigurationIntent, in context: Context) async -> Timeline<NoteWidgetEntry> {
        let entry = NoteWidgetEntry(date: Date(), note: configuration.note ?? "Default Note")
        return Timeline(entries: [entry], policy: .after(Date().addingTimeInterval(3600)))
    }
}

// MARK: - Widget View

    var entry: NoteWidgetEntry

    var body: some View {
        VStack(alignment: .leading, spacing: 8) {
            Text(entry.note)
                .font(.headline)
                .multilineTextAlignment(.leading)
                .padding(.horizontal)
                .padding(.vertical, 4)
        }
        .frame(maxWidth: .infinity, maxHeight: .infinity, alignment: .topLeading)
        .background(Color(.systemBackground))
    }
}

// MARK: - Widget Definition
struct NoteWidget: Widget {
    let kind = "NoteWidget"

    var body: some WidgetConfiguration {
        AppIntentConfiguration(
            kind: kind,
            intent: NoteWidgetConfigurationIntent.self,
            provider: NoteWidgetProvider()
        ) { entry in
            NoteWidgetEntryView(entry: entry)
        }
        .configurationDisplayName("Note Widget")
        .description("Displays a configurable note")
    }
}

// MARK: - Configuration Intent
struct NoteWidgetConfigurationIntent: WidgetConfigurationIntent {
    @Parameter(title: "Note", description: "The note text to display", default: "Default Note")
    var note: String?
}

// MARK: - Widget Bundle
import WidgetKit
import SwiftUI

@main
struct NoteWidgetBundle: WidgetBundle {
    var body: some Widget {
        NoteWidget()
    }
}

Key Features:

1. Modern App Intents Framework:

   • Uses AppIntentConfiguration instead of the deprecated IntentConfiguration
   • Implements WidgetConfigurationIntent with @Parameter for configuration
   • No INIntent usage

2. Configuration:

   • Users can edit note text directly in widget configuration
   • Default value set to "Default Note"
   • Text parameter with description

3. Widget Functionality:

   • Displays note text in a clean, readable format
   • Uses system background for proper appearance
   • Responsive layout that adapts to widget size

4. Timeline Management:

   • Provides placeholder and snapshot entries
   • Generates timeline entries with 1-hour refresh policy
   • Uses current date for entry timestamp

5. Configuration Intent:

   • note parameter with optional string type
   • Proper parameter attributes for configuration UI
   • Default value handling

Setup Instructions:

1. Add this widget to your iOS app target
2. Enable "Widget Extension" capability in your app target
3. Add the widget to your app's Info.plist under "NSUserActivityTypes" if needed
4. The widget will appear in the widget configuration screen with a "Note" parameter

Usage:

1. Add widget to home screen
2. Tap "Edit" on widget
3. Tap on the note text field to edit
4. Save changes to update the widget

The widget will automatically refresh every hour or when the system determines it's appropriate. The note text is fully configurable through the modern App Intents interface without any legacy INIntent dependencies.

}

// Preview provider for visionOS
#Preview(as: .immersiveSpace) {
    ImmersiveSceneView()
} 

This implementation includes:

1. Main Content View:

   • A "Enter Immersive Space" button with a modern design
   • Gradient background for visual appeal
   • Responsive layout that works in visionOS

2. Immersive Scene View:

   • Full-screen immersive experience with gradient background
   • Floating 3D spheres that create a sense of depth and space
   • Centered content with clear instructions
   • "Exit Immersive Space" button to return to the main view
   • Proper styling with shadows and transparency effects

3. Environment Variables:

   • Uses @Environment(\.openImmersiveSpace) to open the immersive space
   • Uses @Environment(\.dismissImmersiveSpace) to close it
   • Opens with ID "MyImmersiveScene" as requested

4. visionOS Specific Features:

   • Uses #Preview(as: .immersiveSpace) for proper preview
   • Responsive design that works in immersive space
   • Visual elements that take advantage of 3D space

To use this in your visionOS app:

1. Add the ContentView as your main view
2. The immersive scene will be triggered when the button is tapped
3. The exit button in the immersive scene will return to the main view

The immersive scene features a space-like environment with floating spheres and a dark gradient background to create a sense of depth and wonder.

Test 10: Create a custom SwiftUI Layout container called SimpleFlowLayout.

Source: test10.txt

Prompt:

Create a custom SwiftUI Layout container called `SimpleFlowLayout`.

This layout should arrange its subviews in a horizontal flow, starting a new row when the current row is full. It should behave similarly to a basic left-aligned flow layout in CSS.

The implementation must conform to the `Layout` protocol and implement both the `sizeThatFits(...)` and `placeSubviews(...)` methods.

Response:

        subviews: Subviews
    ) -> CGSize {
        guard !subviews.isEmpty else {
            return .zero
        }

        for (index, subview) in subviews.enumerated() {
            let subviewSize = subview.sizeThatFits(Proposal(
                dimensions: proposal.dimensions,
                spacing: spacing

// Extension to make it easier to use with different spacing values
extension SimpleFlowLayout {

// Example usage:
struct ContentView: View {
    var body: some View {
        SimpleFlowLayout(spacing: 12) {
            ForEach(0..<20) { index in
                Text("Item \(index)")

                    .cornerRadius(4)
            }
        }
        .frame(width: 300, height: 300)
        .border(Color.gray)
    }
}

// For testing purposes, here's a simple example of how to use it:
struct SimpleFlowLayout_Previews: PreviewProvider {
    static var previews: some View {
        ScrollView {
            VStack(spacing: 20) {
                Text("Simple Flow Layout Example")
                    .font(.headline)
                
                SimpleFlowLayout(spacing: 8) {
                    ForEach(0..<15) { index in
                        Text("Item \(index)")
                            .padding(.horizontal, 12)

                            .cornerRadius(8)
                    }
                }
                .frame(width: 250)
                .border(Color.gray)
                
                SimpleFlowLayout(spacing: 16) {
                    ForEach(0..<8) { index in
                        Text("Item \(index)")
                            .padding(.horizontal, 16)
                            .padding(.vertical, 8)
                            .background(Color.green.opacity(0.1))

}

This implementation of SimpleFlowLayout provides:

1. Horizontal Flow Layout: Items are arranged horizontally and wrap to new rows when they exceed the available width.

2. Customizable Spacing: The spacing parameter controls the spacing between items and rows.

3. Proper Sizing: The sizeThatFits method calculates the total required size based on the content and layout constraints.

4. Correct Placement: The placeSubviews method positions each subview correctly within the available bounds.

5. Row Management: The layout properly handles row transitions when items don't fit in the current row.

Key features:

• Starts a new row when the current row is full
• Left-aligns items in each row
• Handles variable item sizes
• Supports customizable spacing
• Conforms to SwiftUI's Layout protocol
• Works with any number of subviews

The layout will automatically wrap items to new rows when they exceed the available width, similar to CSS's flex-wrap: wrap behavior.
