Can you explain the concept of RunLoop and its role in event handling in applications?

RunLoop is an event processing loop that manages the event queue and tasks in an application. In iOS, it is responsible for receiving events from the system (such as touches, timers, network responses) and processing them. RunLoop allows the application to remain active and responsive, waiting for and handling events as they arrive.

You can think of RunLoop as an infinite loop that:

• Waits for events
• Processes them
• Transitions to waiting for the next event

This helps efficiently utilize resources and maintain smooth interface operation.
