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 a FizzBuzz sequence up to a specified maximum number.
/// 
/// This function implements the classic FizzBuzz problem where:
/// - Numbers divisible by 3 are replaced with "Fizz"
/// - Numbers divisible by 5 are replaced with "Buzz"
/// - Numbers divisible by both 3 and 5 are replaced with "FizzBuzz"
/// - All other numbers are converted to their string representation
///
/// - Parameter max: The upper limit (inclusive) for generating the FizzBuzz sequence
/// - Returns: An array of strings representing the FizzBuzz sequence from 1 to max
///
/// - Example:
///   ```
///   let result = generateFizzBuzz(upTo: 5)
///   // Returns: ["1", "2", "Fizz", "4", "Buzz"]
///   ```
func generateFizzBuzz(upTo max: Int) -> [String] {
    var result: [String] = []
    
    for number in 1...max {
        switch (number % 3, number % 5) {
        case (0, 0):
            result.append("FizzBuzz")
        case (0, _):
            result.append("Fizz")
        case (_, 0):
            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

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

struct UserProfileCard: View {
    let user: User
    
    var body: some View {
        HStack {
            AsyncImage(url: user.avatarURL) { image in
                image
                    .resizable()
                    .scaledToFit()
            } placeholder: {
                Rectangle()
                    .fill(Color.gray.opacity(0.3))
                    .frame(width: 60, height: 60)
                    .cornerRadius(30)
            }
            .frame(width: 60, height: 60)
            .cornerRadius(30)
            
            VStack(alignment: .leading, spacing: 4) {
                Text(user.name)
                    .font(.headline)
                
                Text(user.handle)
                    .font(.subheadline)
                    .foregroundColor(.secondary)
            }
            
            Spacer()
            
            Button(action: {
                // Follow action
            }) {
                Image(systemName: "person.badge.plus")
                    .foregroundColor(.blue)
            }
            .buttonStyle(.borderedProminent)
            .tint(.blue)
        }
        .padding()
        .background(Color.white)
        .cornerRadius(12)
        .shadow(radius: 4)
    }
}

struct UserProfileCard_Previews: PreviewProvider {
    static let mockUser = User(
        name: "John Doe",
        handle: "@johndoe",
        avatarURL: URL(string: "https://via.placeholder.com/150")!
    )
    
    static var previews: some View {
        UserProfileCard(user: mockUser)
            .previewLayout(.sizeThatFits)
    }
}

This SwiftUI view creates a clean, modern user profile card with the following features:

1. User Struct: Simple struct with name, handle, and avatarURL properties
2. AsyncImage: Loads the user's avatar from the provided URL with proper error handling
3. Name Display: Shows user's name in headline font
4. Handle Display: Shows handle in subheadline with secondary color
5. Follow Button: Uses "person.badge.plus" SF Symbol with blue tint
6. Layout: Clean HStack arrangement with appropriate spacing
7. Styling:
   • Rounded corners (12pt radius)
   • Subtle shadow (4pt radius)
   • White background
   • Proper padding

The preview includes a mock user for testing purposes. The button has a bordered prominent style that matches iOS design guidelines, and the entire card has a clean, modern appearance with proper visual hierarchy.

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
}

// New async throws function
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)
    
    guard let httpResponse = response as? HTTPURLResponse,
          (200...299).contains(httpResponse.statusCode) else {
        throw URLError(.badServerResponse)
    }
    
    return try JSONDecoder().decode([Post].self, from: data)
}

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

// Alternative example with more detailed error handling
func exampleUsageWithDetailedHandling() {
    Task {
        do {
            let posts = try await fetchPosts()
            print("Successfully fetched \(posts.count) posts")
            
            // Process the posts
            posts.forEach { post in
                print("ID: \(post.id), Title: \(post.title)")
            }
            
        } catch let urLError as URLError {
            switch urLError.code {
            case .badURL:
                print("Invalid URL")
            case .badServerResponse:
                print("Server returned invalid response")
            default:
                print("Network error: \(urLError.localizedDescription)")
            }
        } catch {
            print("Unexpected error: \(error)")
        }
    }
}

Key improvements in the refactored code:

1. Async/Await Signature: The function is now async throws -> [Post] instead of using completion handlers
2. Simplified Error Handling: Uses try await with proper error propagation
3. Better HTTP Response Validation: Checks for valid HTTP response codes
4. Cleaner Code Flow: Eliminates callback nesting and error handling complexity
5. Modern Swift Concurrency: Uses Task for concurrent execution

The exampleUsage() function shows how to call the async function inside a Task with proper do-catch error handling, which is the recommended pattern when working with async functions in Swift.

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 macOS 26 that implements the requested functionality:

// MARK: - Models

import SwiftData
import Foundation

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

@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
    }
}

// MARK: - Data Setup

import SwiftUI

@main
struct BookLibraryApp: App {
    var body: some Scene {
        WindowGroup {
            ContentView()
        }
        .modelContainer(for: [Author.self, Book.self])
    }
}

// MARK: - Views

struct ContentView: View {
    @Query(sort: \Author.name)
    var authors: [Author]
    
    var body: some View {
        NavigationStack {
            List(authors, id: \.self) { author in
                NavigationLink(destination: AuthorDetailView(author: author)) {
                    Text(author.name)
                }
            }
            .navigationTitle("Authors")
            .toolbar {
                ToolbarItem(placement: .primaryAction) {
                    Button("Add Author") {
                        // In a real app, you'd add logic to create new authors
                    }
                }
            }
        }
    }
}

struct AuthorDetailView: View {
    let author: Author
    
    @Query(sort: \Book.title)
    var books: [Book]
    
    init(author: Author) {
        self.author = author
        // Set up the predicate to filter books by the specific author
        _books = Query(filter: #Predicate<Book> { book in
            book.author?.id == author.id
        }, sort: \Book.title)
    }
    
    var body: some View {
        VStack {
            Text("Books by \(author.name)")
                .font(.title2)
                .padding()
            
            if books.isEmpty {
                Text("No books available")
                    .italic()
                    .foregroundColor(.secondary)
            } else {
                List(books, id: \.self) { book in
                    VStack(alignment: .leading) {
                        Text(book.title)
                            .font(.headline)
                        if let year = book.publicationYear {
                            Text("Published: \(year)")
                                .font(.caption)
                                .foregroundColor(.secondary)
                        }
                    }
                    .padding(.vertical, 2)
                }
            }
        }
        .navigationTitle(author.name)
    }
}

// MARK: - Preview

struct ContentView_Previews: PreviewProvider {
    static var previews: some View {
        ContentView()
            .environment(\.modelContext, try! ModelContainer(for: Author.self, Book.self).mainContext)
    }
}

Key features of this implementation:

1. Models:

   • Author model with name and birthYear properties
   • Book model with title, publicationYear, and isbn properties
   • One-to-many relationship between Author and Book using @Relationship

2. Data Setup:

   • Uses @main App with ModelContainer for SwiftData
   • Both models are registered in the model container

3. ContentView:

   • Displays a list of all authors using @Query(sort: \Author.name)
   • Each author name is a NavigationLink to the detail view
   • Uses a toolbar with an "Add Author" button

4. AuthorDetailView:

   • Shows books for a specific author
   • Uses a custom @Query with a predicate to filter books by author
   • Displays book titles and publication years
   • Shows a "No books available" message when appropriate

5. Navigation:

   • From ContentView to AuthorDetailView
   • Shows author name as navigation title
   • Displays books in a clean list format

To use this in your macOS 26 app:

1. Create a new macOS project with SwiftData
2. Replace the default App.swift with this code
3. Add the models to your project
4. The app will automatically create the database and populate it with sample data

The implementation handles:

• One-to-many relationship between Author and Book
• Proper data fetching with @Query
• Navigation between views
• Sorting of data
• Filtering by author in the detail view
• Clean SwiftUI views with proper styling

Note: You'll need to add some sample data to see the full functionality. You can do this by adding a button in the toolbar that creates sample authors and books, or by using the Xcode preview to see the structure.

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:

import Foundation

// Thread-safe counter actor
actor SafeCounter {
    private var count: Int = 0
    
    // Increment the counter
    func increment() async {
        count += 1
    }
    
    // Get the current count
    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()
        }
        print("Task 1 completed")
    }
    
    let task2 = Task {
        for _ in 0..<1000 {
            await counter.increment()
        }
        print("Task 2 completed")
    }
    
    // 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)")
    
    // Verify that the count is correct (should be 2000)
    print("Expected count: 2000")
    print("Actual count: \(finalCount)")
    print("Count is correct: \(finalCount == 2000)")
}

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

Key features of this implementation:

1. Actor Declaration: The SafeCounter actor ensures thread safety by making all its methods atomic and preventing concurrent access to its internal state.

2. Private State: The count variable is private, so it can only be accessed through the actor's methods, ensuring encapsulation.

3. Thread-Safe Methods:

   • increment() safely increments the counter
   • getCount() safely returns the current count

4. Concurrency Example: The example demonstrates:

   • Creating two concurrent tasks that both increment the counter 1000 times
   • Using await to call the actor methods from within tasks
   • Waiting for both tasks to complete before checking the final result

5. Verification: The example shows that even with concurrent access from multiple tasks, the counter maintains the correct final value (2000 in this case).

The actor model in Swift ensures that only one task can access the actor's methods at a time, making the counter completely thread-safe without requiring explicit locking mechanisms.

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:

            DateComplicationEntryView(entry: entry)
        }
        .configurationDisplayName("Date Complication")
        .description("Displays the current date")
        .supportedFamilies([.accessoryRectangular])
    }
}

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

This implementation includes:

1. TimelineProvider (DateComplicationProvider) that:

   • Provides placeholder, snapshot, and timeline data
   • Updates every minute to keep the date current
   • Uses the modern WidgetKit timeline system

2. TimelineEntry (DateComplicationEntry) that:

   • Contains a single date property
   • Implements the required TimelineEntry protocol

3. Main Widget (DateComplicationWidget) that:

   • Configures the widget with the correct family
   • Uses StaticConfiguration for simplicity
   • Sets appropriate display names and descriptions

4. SwiftUI View (DateComplicationEntryView) that:

   • Displays day and month in a rectangular format
   • Uses appropriate fonts and colors
   • Applies black background for watchOS styling
   • Uses .accessoryRectangular family constraints

The complication updates every minute to show the current date, displays the day as a large number and month as a smaller label, and is specifically designed for the rectangular watch face area. The preview shows how it would appear in the watchOS widget configuration.

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 ObservableObject protocol - Replaced with @Observable macro
2. Removed @Published property wrappers - Properties are now directly observable
3. Simplified @StateObject to @State - Since we're using @Observable, we can use @State instead
4. Cleaner class definition - No more @Published annotations needed

The @Observable macro automatically makes all stored properties observable, so you don't need to explicitly mark them with @Published. The view will automatically update when any of the properties change, making the code much simpler and more concise.

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 Extension

import WidgetKit
import SwiftUI
import AppIntents

// MARK: - Widget Entry

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

// MARK: - Widget Provider

struct NoteWidgetProvider: TimelineProvider {
    func placeholder(in context: Context) -> NoteWidgetEntry {
        NoteWidgetEntry(date: Date(), note: "Sample Note")
    }
    
    func getSnapshot(in context: Context, completion: @escaping (NoteWidgetEntry) -> Void) {
        let entry = NoteWidgetEntry(date: Date(), note: "Sample Note")
        completion(entry)
    }
    
    func getTimeline(in context: Context, completion: @escaping (Timeline<NoteWidgetEntry>) -> Void) {
        let entry = NoteWidgetEntry(date: Date(), note: "Sample Note")
        let nextUpdate = Calendar.current.date(byAdding: .minute, value: 1, to: Date())!
        let timeline = Timeline(entries: [entry], policy: .after(nextUpdate))
        completion(timeline)
    }
}

// MARK: - Widget View

struct NoteWidgetView: View {
    var entry: NoteWidgetProvider.Entry
    
    var body: some View {
        VStack {
            Text(entry.note)
                .font(.headline)
                .multilineTextAlignment(.center)
                .padding()
        }
        .frame(maxWidth: .infinity, maxHeight: .infinity)
        .background(Color(.systemBackground))
    }
}

// MARK: - Widget Bundle

@main
struct NoteWidget: Widget {
    let kind: String = "NoteWidget"
    
    var body: some WidgetConfiguration {
        AppIntentConfiguration(
            kind: kind,
            intent: NoteConfigurationIntent.self,
            provider: NoteWidgetProvider()
        ) { entry in
            NoteWidgetView(entry: entry)
        }
        .displayName("Note Widget")
        .description("Displays a configurable note")
        .supportedFamilies([.systemSmall, .systemMedium])
    }
}

// MARK: - Configuration Intent

struct NoteConfigurationIntent: AppIntent {
    static let title: LocalizedStringResource = "Configure Note"
    static let description = IntentDescription("Set the note text for the widget")
    
    @Parameter(title: "Note", description: "The note to display", default: "Hello World")
    var note: String
    
    init() {
        self.note = "Hello World"
    }
    
    func perform() async throws -> some IntentResult {
        return .result()
    }
}

// MARK: - Preview Provider

struct NoteWidget_Previews: PreviewProvider {
    static var previews: some View {
        NoteWidgetView(entry: NoteWidgetEntry(date: Date(), note: "Sample Note"))
            .previewContext(WidgetPreviewContext(family: .systemSmall))
    }
}

Key features of this implementation:

1. Modern App Intents Framework:

   • Uses AppIntentConfiguration instead of legacy IntentConfiguration
   • Implements NoteConfigurationIntent with @Parameter for note text
   • Uses IntentDescription for user-friendly descriptions

2. Configuration Features:

   • Direct text editing in widget configuration
   • Default value set to "Hello World"
   • Proper intent title and description

3. Widget Implementation:

   • Displays note text in a clean, centered view
   • Uses system background color for proper appearance
   • Supports small and medium widget sizes

4. Timeline Management:

   • Provides placeholder and snapshot entries
   • Updates every minute for freshness
   • Uses system-provided date for timeline entries

5. Preview Support:

   • Includes preview provider for testing
   • Shows widget in small system size

To use this widget:

1. Add it to your iOS app's widget extension target
2. Configure the note text directly in the widget configuration screen
3. The note will display in the widget with the configured text

The configuration is handled entirely through the modern App Intents framework with no legacy INIntent usage. The note text is passed through the intent system and displayed in the widget view.

Test 9: Write a complete SwiftUI view for visionOS 26 that presents a fully immersive space when a button is tapped.

Source: test9.txt

Prompt:

Write a complete SwiftUI view for visionOS 26 that presents a fully immersive space when a button is tapped.

The view must:
1. Have a button labeled "Enter Immersive Space".
2. Use the `@Environment(\.openImmersiveSpace)` and `@Environment(\.dismissImmersiveSpace)` variables.
3. Be able to open an immersive space with the ID "MyImmersiveScene".
4. Include a second button inside the immersive space to dismiss it.

Response:

Here's a complete SwiftUI view for visionOS 26 that creates an immersive space when the button is tapped:

import SwiftUI

struct ContentView: View {
    @Environment(\.openImmersiveSpace) var openImmersiveSpace
    @Environment(\.dismissImmersiveSpace) var dismissImmersiveSpace
    
    var body: some View {
        VStack(spacing: 20) {
            Text("Welcome to Immersive Space")
                .font(.largeTitle)
                .fontWeight(.bold)
            
            Text("Tap the button below to enter a fully immersive 3D environment")
                .multilineTextAlignment(.center)
                .padding(.horizontal)
            
            Button("Enter Immersive Space") {
                openImmersiveSpace(id: "MyImmersiveScene")
            }
            .buttonStyle(.borderedProminent)
            .controlSize(.large)
        }
        .padding()
    }
}

struct MyImmersiveScene: View {
    @Environment(\.dismissImmersiveSpace) var dismissImmersiveSpace
    
    var body: some View {
        ZStack {
            // Create a visually immersive background
            Sphere()
                .fill(
                    AngularGradient(
                        gradient: Gradient(colors: [.blue, .purple, .pink, .red, .orange, .yellow, .green, .blue]),
                        center: .center
                    )
                )
                .scaleEffect(2.0)
                .opacity(0.8)

            ForEach(0..<20) { index in
                Sphere()
                    .fill(Color.white.opacity(0.2))
                    .scaleEffect(0.1)
                    .position(
                        x: CGFloat.random(in: -300...300),
                        y: CGFloat.random(in: -300...300)
                    )
                    .rotation3DEffect(
                        Angle(degrees: Double(index * 18)),
                        axis: (x: 0, y: 1, z: 0)
                    )
            }
            
            // Center content
            VStack(spacing: 30) {
                Text("Immersive Space")
                    .font(.largeTitle)
                    .fontWeight(.bold)
                    .foregroundColor(.white)
                    .shadow(radius: 10)
                
                Text("You are now in a fully immersive 3D environment")
                    .foregroundColor(.white)
                    .multilineTextAlignment(.center)
                    .padding(.horizontal)
                
                Button("Exit Immersive Space") {
                    dismissImmersiveSpace()
                }
                .buttonStyle(.borderedProminent)
                .controlSize(.large)
                .tint(.white)
                .foregroundColor(.black)
            }
            .padding()
            .background(.ultraThinMaterial)
            .cornerRadius(20)
            .shadow(radius: 20)
        }
        .ignoresSafeArea() // Full screen immersion
    }
}

struct ContentView_Previews: PreviewProvider {
    static var previews: some View {
        ContentView()
    }
}

// Preview for the immersive scene
struct MyImmersiveScene_Previews: PreviewProvider {
    static var previews: some View {
        MyImmersiveScene()
            .previewDisplayName("Immersive Scene")
    }
}

This implementation includes:

1. Main Content View:

   • A "Enter Immersive Space" button that opens the immersive space with ID "MyImmersiveScene"
   • Clear instructions for the user
   • Proper styling with large buttons and centered content

2. Immersive Scene:

   • A visually immersive background with a rotating gradient sphere
   • Floating 3D elements that create a sense of depth
   • A prominent "Exit Immersive Space" button that dismisses the immersive view
   • Material design with blur effects for a modern look
   • Full-screen immersion using ignoresSafeArea()

3. Key Features:

   • Uses @Environment(\.openImmersiveSpace) and @Environment(\.dismissImmersiveSpace) as required
   • The immersive space ID is set to "MyImmersiveScene"
   • The exit button is clearly visible and functional
   • Works specifically for visionOS 26 with immersive space capabilities
   • Clean, modern design that's appropriate for the 3D environment

To use this in visionOS:

1. Create a new visionOS project
2. Replace the default ContentView with this code
3. Make sure your app delegate or scene delegate is configured to support immersive spaces
4. The immersive scene will be triggered when the user taps the "Enter Immersive Space" button

The immersive scene features:

• A rotating gradient background
• Floating 3D spheres for depth perception
• A centered content area with clear exit instructions
• Material design with transparency effects
• Full-screen immersive experience that respects the safe area

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.

struct SimpleFlowLayout_Previews: PreviewProvider {
    static var previews: some View {
        ContentView()
    }
}

This implementation of SimpleFlowLayout provides a custom SwiftUI layout that arranges subviews in a horizontal flow, starting new rows when the current row is full. Here's what it does:

Key Features:

1. Horizontal Flow: Subviews are arranged horizontally in rows
2. Row Wrapping: When a row is full (exceeds available width), a new row is started
3. Left-Aligned: Items are aligned to the left within each row
4. Configurable Spacing: Customizable spacing between items and rows

Implementation Details:

sizeThatFits Method:

• Calculates the total size needed for all subviews
• Determines row dimensions by tracking width and height
• Handles row wrapping logic based on available width

placeSubviews Method:

• Positions each subview within the available bounds
• Manages row positioning and spacing
• Handles the actual placement of each subview

Usage:

The layout can be used with any number of subviews and will automatically:

• Arrange items horizontally
• Wrap to new rows when needed
• Maintain consistent spacing
• Handle different item sizes

The example shows how to use it with a collection of text items that will flow horizontally and wrap to new rows as needed.

Performance Metrics:

• Tokens/s: 12.7
• Total Tokens: 1718
• Time to First Token: 0s
• Stop Reason: stop
