ARC in Swift

ARC (Automatic Reference Counting) in Swift is a memory management system that automatically tracks and manages the lifecycle of objects. It keeps a count of how many parts of your program are using each object. When an object is no longer needed (the count drops to zero), ARC automatically releases the memory it occupied. This process helps prevent memory leaks and ensures efficient use of resources without requiring manual deallocation, allowing developers to write safer and cleaner code while relying on Swift to handle memory management behind the scenes.
