Custom Entry Point in iOS App

This repository demonstrates how to create a custom entry point in an iOS application using Swift. As an example, an Application object posts a notification whenever a user begins an interaction with the app.

Introduction

By default, iOS applications use the @UIApplicationMain (@main in Swift 5.3) attribute to create an entry point for the app. However, there are scenarios where you might need more control over the application's lifecycle, requiring a custom entry point.

Steps to create a custom entry point

1. Remove @UIApplicationMain attribute

Remove the @UIApplicationMain (or @main in Swift 5.3) attribute from your AppDelegate class.

2. Create a main.swift file

Create a new file named main.swift and define the custom entry point calling UIAplicationMain function

(Optional) 3. Create Application class

Create your custome Application class and override its methods

Conclusion

By following these steps, you can create a custom entry point for your iOS application, providing greater control over its initialization and configuration.
