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 maximum number.
/// - Parameter max: The maximum number in the sequence.
/// - Returns: An array of strings representing the FizzBuzz sequence.
func generateFizzBuzz(upTo max: Int) -> [String] {
var result = [String]()
for i in 1...max {
if i % 3 == 0 && i % 5 == 0 {
result.append("FizzBuzz")
} else if i % 3 == 0 {
result.append("Fizz")
} else if i % 5 == 0 {
result.append("Buzz")
} else {
result.append(String(i))
}
}
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:
Here's how you can create a UserProfileCard view in SwiftUI that meets all of your requirements:
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(spacing: 16) {
AsyncImage(url: user.avatarURL) { image in
image.resizable()
} placeholder: {
Color.gray
}
.frame(width: 50, height: 50)
.clipShape(Circle())
VStack(alignment: .leading, spacing: 4) {
Text(user.name)
.font(.headline)
Text("@\(user.handle)")
.font(.subheadline)
.foregroundColor(.secondary)
}
Spacer()
Button(action: {
// Add your follow action here
}) {
Image(systemName: "person.badge.plus")
}
}
.padding()
.background(Color.white)
.cornerRadius(10)
.shadow(color: Color.black.opacity(0.1), radius: 5, x: 0, y: 2)
}
}
This code creates a UserProfileCard view that displays the user's avatar, name, handle, and a "Follow" button. The card has rounded corners and a subtle shadow for depth.

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 how you can refactor the old networking code to use modern Swift Concurrency with async/await:
struct Post: Codable {
let id: Int
let title: String
}
func fetchPosts() async throws -> [Post] {
guard let url = URL(string: "https://api.example.com/posts") else { throw URLError(.badURL) }
let (data, _) = try await URLSession.shared.data(from: url)
return try JSONDecoder().decode([Post].self, from: data)
}
You can call this new async function inside a Task with a do-catch block like so:
Task {
do {
let posts = try await fetchPosts()
// Use the fetched posts here...
} catch {
print("Error: \(error)")
}
}

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 simple example of how you could define your models and views in SwiftUI using SwiftData.
First, let's define our models:
import Foundation
import SwiftData
@Model
class Author {
var name: String
@Relationship(deleteRule: .cascade)
var books: [Book]?
init(name: String) {
self.name = name
}
}
@Model
class Book {
var title: String
var author: Author?
init(title: String, author: Author?) {
self.title = title
self.author = author
}
}
Now let's create our views. First, the view that displays a list of all authors:
import SwiftUI
import SwiftData
struct AuthorListView: View {
@Environment(\.modelContext) private var context
@Query(sortBy: \Author.name) private var authors: [Author]
var body: some View {
NavigationStack {
List(authors) { author in
NavigationLink(author.name, value: author)
}
.navigationDestination(for: Author.self) { author in
BookListView(author: author)
}
}
}
}
Then, the detail view that shows a list of all books written by a specific author:
struct BookListView: View {
let author: Author
@Environment(\.modelContext) private var context
@Query(sortBy: \Book.title, predicate: #Predicate<Book>{"$0.author == %@", author}) private var books: [Book]
var body: some View {
List(books) { book in
Text(book.title)
}
.navigationTitle("Books by \(author.name)")
}
}
Finally, don't forget to add the @main attribute to your main SwiftUI view and initialize a model context:
import SwiftUI
import SwiftData
@main
struct YourApp: App {
var body: some Scene {
WindowGroup {
AuthorListView()
.modelContainer(for: [Author.self, Book.self])
}
}
}

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 = 0
func increment() async {
count += 1
}
func getCount() async -> Int {
return count
}
}
You can create an instance of the actor and call its methods concurrently from two different Tasks like this:
let safeCounter = SafeCounter()
Task {
for _ in 0..<10 {
await safeCounter.increment()
}
}
Task {
for _ in 0..<5 {
let count = await safeCounter.getCount()
print("Current count: \(count)")
}
}
In this example, we create a SafeCounter instance and then launch two concurrent tasks. The first task increments the counter 10 times, while the second task prints the current count 5 times. Since the SafeCounter actor is thread-safe, it ensures that the increment and getCount operations are performed atomically, preventing any race conditions or inconsistent results.

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 is a simple example of how you can create a watchOS 26 complication that displays the current date in the .accessoryRectangular family using SwiftUI and WidgetKit.
import WidgetKit
import SwiftUI
struct SimpleDateProvider: TimelineProvider {
func getSnapshot(in context: Context, completion: @escaping (SimpleEntry) -> Void) {
let entry = SimpleEntry(date: Date())
completion(entry)
}
func getTimeline(in context: Context, completion: @escaping (Timeline<SimpleEntry>) -> Void) {
var entries: [SimpleEntry] = []
// Generate a new entry every minute.
let currentDate = Date()
for hour in 0 ..< 24 {
for minute in 0 ..< 60 {
let dateComponents = Calendar.current.dateComponents([.year, .month, .day, .hour, .minute], from: currentDate)
var newComponents = DateComponents()
newComponents.year = dateComponents.year
newComponents.month = dateComponents.month
newComponents.day = dateComponents.day
newComponents.hour = hour
newComponents.minute = minute
let entryDate = Calendar.current.date(from: newComponents)!
let entry = SimpleEntry(date: entryDate)
entries.append(entry)
}
}
let timeline = Timeline(entries: entries, policy: .atEnd)
completion(timeline)
}
}
struct SimpleEntry: TimelineEntry {
let date: Date
}
struct SimpleWidget: Widget {
private let kind: String = "SimpleWidget"
public var body: some WidgetConfiguration {
StaticConfiguration(kind: kind, provider: SimpleDateProvider()) { entry in
SimpleWidgetView(entry: entry)
}
.supportedFamilies([.accessoryRectangular])
}
}
struct SimpleWidgetView : View {
var entry: SimpleEntry
var body: some View {
Text(entry.date, style: .date)
.font(.headline)
}
}
This code creates a simple widget that displays the current date in the accessoryRectangular family. The SimpleDateProvider generates timeline entries every minute for the rest of the day. The SimpleWidgetView is a SwiftUI view that displays the date from the entry.

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:
With the introduction of Swift 5.9, we can use the @Observable macro to simplify our code and make it more modern. Here's how you can refactor your code:
@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)
}
}
}
In this refactored code, we've removed the ObservableObject protocol and the @Published property wrapper from our UserSettings class. Instead, we've used the new @Observable macro to make all properties of the UserSettings class observable. This means that any changes to these properties will automatically trigger updates in any views that are using them.
In the SettingsView, we've also removed the @StateObject property wrapper and replaced it with @State. This is because we no longer need to create a separate instance of our UserSettings class for each view, as the @Observable macro takes care of this automatically.

Test 8: 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.
Source: test8.txt
Prompt:
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:
Creating a WidgetKit widget with configurable content using the new App Intents framework involves several steps. Here is an example of how you can create such a widget.
First, define your intent in the Intents file:
import AppIntents
struct NoteIntent: AppIntent {
static let title = "Note"
@Parameter(title: "Content") var noteText: String?
}
Then, create a widget structure that conforms to Widget protocol and use the intent for configuration.
import WidgetKit
import SwiftUI
struct NoteWidget: Widget {
let kind: String = "NoteWidget"
var noteText: String?
var body: some WidgetConfiguration {
IntentConfiguration(kind: kind, intent: NoteIntent.self, content: { config in
Text(config.noteText ?? "")
.padding()
})
}
}
Finally, create a widget view that will be displayed when the user taps on the widget. This view should also allow editing of the note text.
struct NoteWidgetView: View {
@State private var noteText = ""
var body: some View {
TextField("Enter your note", text: $noteText)
.padding()
}
}
To allow the user to edit the note's text directly from the widget's configuration screen, you can use WidgetConfigurationIntentView. This view allows users to interact with intents and update their configurations.
struct NoteWidgetConfigurationView: View {
var body: some View {
WidgetConfigurationIntentView(NoteIntent.self) { intent in
TextField("Enter your note", text: Binding<String>(
get: { intent.noteText ?? "" },
set: { intent.noteText = $0 }
))
.padding()
}
}
}
Remember to add the widget to your WidgetBundle.
struct NoteWidgetBundle: WidgetBundle {
var body: some Widget {
NoteWidget()
}
}

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 is a simple SwiftUI view that meets all of your requirements:
import SwiftUI
import RealityKit
struct ContentView: View {
@Environment(\.openImmersiveSpace) var openImmersiveSpace
@State private var immersiveSpaceIsShown = false
var body: some View {
if immersiveSpaceIsShown {
ImmersiveSpace(id: "MyImmersiveScene") {
Button("Dismiss Immersive Space") {
immersiveSpaceIsShown = false
}
}
} else {
Button("Enter Immersive Space") {
openImmersiveSpace(id: "MyImmersiveScene") {
immersiveSpaceIsShown = true
}
}
}
}
}
This view will display a button labeled "Enter Immersive Space". When this button is tapped, it will open an immersive space with the ID "MyImmersiveScene". Inside this immersive space, there will be another button labeled "Dismiss Immersive Space" that, when tapped, will dismiss the immersive space and return to the original view.

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:
Here's an example of how you could implement this custom SwiftUI Layout container called SimpleFlowLayout. This layout will arrange its subviews in a horizontal flow, starting a new row when the current row is full.
import SwiftUI
struct SimpleFlowLayout: Layout {
let itemSpacing: CGFloat
func sizeThatFits(proposal: ProposedViewSize, subviews: Subviews, cache: inout ()) -> CGSize {
guard !subviews.isEmpty else { return .zero }
var remainingWidth = proposal.recommendedSize.width
var maxHeight: CGFloat = 0
var currentRowHeight: CGFloat = 0
for subview in subviews {
let size = subview.sizeThatFits(proposal)
if remainingWidth - size.width < 0 {
maxHeight += currentRowHeight
currentRowHeight = 0
remainingWidth = proposal.recommendedSize.width
}
remainingWidth -= size.width + itemSpacing
currentRowHeight = max(currentRowHeight, size.height)
}
return CGSize(width: proposal.recommendedSize.width, height: maxHeight + currentRowHeight)
}
func placeSubviews(in bounds: CGRect, proposal: ProposedViewSize, subviews: Subviews, cache: inout ()) {
var x = bounds.minX
var y = bounds.minY
var remainingWidth = bounds.width
for subview in subviews {
let size = subview.sizeThatFits(proposal)
if remainingWidth - size.width < 0 {
x = bounds.minX
y += size.height + itemSpacing
remainingWidth = bounds.width
}
subview.place(at: CGPoint(x: x, y: y), proposal: ProposedViewSize(size))
x += size.width + itemSpacing
remainingWidth -= size.width + itemSpacing
}
}
}
You can use this layout in your SwiftUI views like so:
struct ContentView: View {
var body: some View {
ScrollView {
SimpleFlowLayout(itemSpacing: 10) {
ForEach(0..<20) { index in
Text("Item \(index)")
.padding()
.border(Color.gray)
}
}
}
}
}
