Day 16: Alerts – Designing Native Alerts in SwiftUI 🚨

Today, we’ll focus on using the native alert options available in SwiftUI.

SwiftUI provides a straightforward way to display alerts like this:

Why Use Native Alerts?

Simplicity: SwiftUI’s native alerts are easy to implement and require minimal code.
System Integration: They provide a familiar look and feel, ensuring consistency across iOS applications.
Accessibility: Native alerts come with built-in accessibility support, making your app more user-friendly.

Code Example: Creating a Native Alert

import SwiftUI

struct ContentView: View {
    @State private var showAlert = false // State variable to control alert visibility

    var body: some View {
        VStack {
            Button("Show Alert") {
                showAlert.toggle() // Toggle alert visibility
            }
            .alert(isPresented: $showAlert) { // Present the alert when showAlert is true
                Alert(
                    title: Text("Alert Title"), // Title of the alert
                    message: Text("This is an alert message."), // Message to display
                    primaryButton: .default(Text("Confirm")) {
                        // Action to perform on Confirm
                        print("Confirmed!")
                    },
                    secondaryButton: .cancel() // Action to perform on Cancel
                )
            }
        }
        .padding()
    }
}
