UIKit App Delegate

The UIKit App Delegate is like the manager of an iOS app, overseeing its launch and overall behavior. It handles key events, such as starting up, entering the background, or terminating, ensuring the app responds appropriately. Think of it as the coordinator that initializes the app, sets up the user interface, and manages transitions between different states. Developers use this component to customize what happens during these lifecycle events, making sure the app runs smoothly and provides a good user experience from launch to closure.
