How to show alert in SwiftUI (iOS 15+)

Starting iOS 15 and above, Alert has been moved into presentation modifiers area meaning it’s now an alert modifier rather than a struct.

In this article, we will explore alerts in SwiftUI for iOS 15+.

alert modifier is used to show an alert when we want the user to act in response to the state of the app.

To show an alert, we create a boolean state variable which determines if the alert should be visible or not.

@State private var showAlert = false

From there, we attach alert modifier passing State variable as isPresented parameter along with the buttons we want to show in the alert.

.alert("This is an alert", isPresented: $showAlert) { 
    Button("OK") {}
    Button("Not OK") {}
}

We launch the alert by toggling the State variable.

showAlert.toggle()

struct DevTechieAlertsExample: View {
    @State private var showAlert = false
    var body: some View {
        NavigationView {
