Here’s a simple counter app using SwiftUI that increments a counter each time a button is pressed:

import SwiftUI

struct CounterView: View {
    // State to hold the count
    @State private var count = 0
    
    var body: some View {
        VStack {
            Text("Counter: \(count)")
                .font(.largeTitle)
                .padding()
            
            Button(action: {
                // Action to increment the count
                count += 1
            }) {
                Text("Increment")
                    .font(.headline)
                    .padding()
                    .foregroundColor(.white)
                    .background(Color.blue)
                    .cornerRadius(10)
            }
            .padding()
        }
    }
}

import SwiftUI

@main
struct CounterApp: App {
    var body: some Scene {
        WindowGroup {
            CounterView()
        }
    }
}

Explanation:

1. CounterView Struct:
   • @State private var count = 0: Defines a state property count to hold the current count value. The @State property wrapper is used here because changes to count will cause SwiftUI to update the view automatically.
   • Text("Counter: \(count)"): Displays the current value of count.
   • Button(action: { ... }) { ... }: Creates a button labeled “Increment” with an action closure that increments the count by 1 when pressed.
2. Button Styling:
   • .font(.headline): Sets the font size to headline.
   • .padding(): Adds padding around the button text.
   • .foregroundColor(.white): Sets the text color to white.
   • .background(Color.blue): Sets the background color to blue.
   • .cornerRadius(10): Rounds the corners of the button.
3. CounterApp Struct:
   • WindowGroup: Sets up the main window of the app with CounterView as its root view.

How to Use:

• Copy the above code into a SwiftUI project in Xcode.
• Run the project on a simulator or device.
• You should see a screen with “Counter: 0” and a button labeled “Increment”.
• Each time you tap the “Increment” button, the counter value should increase by one.
