AlertViewModifiersDemo

A SwiftUI project demonstrating reusable, composable view modifiers for presenting custom alerts.

Demo

The Problem

SwiftUI’s native .alert view modifier can become repetitive and rigid when you want to:

• Show a simple alert with a button.
• Customize alert content beyond a basic message.
• Collect user input (using text fields) inside an alert.

Manually managing isPresented booleans and duplicating .alert logic across views makes code harder to maintain.

Common Scenario

• You want to show a simple confirmation alert across multiple screens.
• You need a text field inside an alert to update user information.
• You want reusable, composable alert logic without cluttering your views.

This Project’s Solution

This demo introduces a set of SwiftUI view modifiers to simplify and extend alert usage:

showingAlert

.showingAlert("Title", message: "Message", isPresented: $isPresented)

• Displays a basic alert with a customizable button and optional completion action.

---

customAlert

.customAlert("Message", isPresented: $isPresented) {
    // Custom view content inside the alert
    Button("Confirm") { }
}

• Injects custom SwiftUI views into an alert for more flexible interactions.

---

singleFieldAlert

.singleFieldAlert("Enter name", isPresented: $isPresented) { text in
    // Handle text input
}

• Presents an alert with a text field, captures user input, and clears the field automatically when dismissed.

---

Demo Project Includes

Two sections showcasing:

• A simple alert using showingAlert.
• A text field alert using singleFieldAlert to update user information.

This demo mirrors real-world use cases where clean, reusable alert presentation improves SwiftUI apps.

These modifiers are part of NnSwiftUIKit, a collection of custom SwiftUI view modifiers and utilities.
