SwiftUI is Apple's modern declarative framework for building user interfaces across all Apple platforms. Here's how it compares to UIKit:

## Key Differences

**SwiftUI (Declarative)**
- Describe WHAT the UI should look like
- State-driven updates
- Less boilerplate code
- Cross-platform by default

**UIKit (Imperative)**
- Describe HOW to build the UI step-by-step
- Manual state management
- More verbose
- iOS/tvOS focused

## Example

```swift
// SwiftUI
struct ContentView: View {
    @State private var count = 0
    
    var body: some View {
        VStack {
            Text("Count: \\(count)")
            Button("Increment") {
                count += 1
            }
        }
    }
}
```

```swift
// UIKit equivalent
class ViewController: UIViewController {
    var count = 0
    let label = UILabel()
    let button = UIButton()
    
    override func viewDidLoad() {
        super.viewDidLoad()
        setupUI()
    }
    
    @objc func incrementTapped() {
        count += 1
        label.text = "Count: \\(count)"
    }
    
    func setupUI() {
        // ... lots more setup code
    }
}
```

SwiftUI is recommended for new projects, especially if targeting iOS 14+ and multiple platforms.

    )
    
    static let mockUser2 = Message(
        role: .user,
        content: "Can you explain async/await in Swift?",
        tokens: 8,
        cost: 0.00001

        content: """
Async/await is Swift's modern concurrency model introduced in Swift 5.5. It makes asynchronous code look and behave like synchronous code.

## Basic Example

```swift
// Old way with completion handlers
func fetchData(completion: @escaping (Result<Data, Error>) -> Void) {
    URLSession.shared.dataTask(with: url) { data, response, error in
        if let error = error {
            completion(.failure(error))
        } else if let data = data {
            completion(.success(data))
        }
    }.resume()
}

// New way with async/await
func fetchData() async throws -> Data {
    let (data, _) = try await URLSession.shared.data(from: url)
    return data
}
```

## Key Benefits

1. **Readability**: No callback pyramids
2. **Error handling**: Standard try/catch
3. **Sequential logic**: Reads top-to-bottom
4. **Cancellation**: Built-in with Task

## Usage

```swift
Task {
    do {
        let data = try await fetchData()
        await MainActor.run {
            // Update UI
        }
    } catch {
        print("Error: \\(error)")
    }
}
```

Much cleaner than completion handlers!
