Concept

Alert is used in SwiftUI to show important messages or ask the user to make a quick decision.

It allows apps to:

display warnings
show important information
ask for confirmation

Core flow:

Button / State Change → Alert Appears → User Chooses Action

What It Does

An alert presents a system dialog on top of the current screen.

It is commonly used for:

warnings
errors
confirmations
critical user actions

The alert usually contains:

a title
a message
one or more buttons

Basic Structure

.alert("Title", isPresented: $showAlert) {
    Button("OK") { }
} message: {
    Text("Message")
}

Here:

"Title" → alert title
isPresented → controls when alert appears
Button → user action
Text("Message") → alert message
