What is the main function of automatic memory management implemented through ARC?.

The main function of automatic memory management using ARC (Automatic Reference Counting) is to count references to objects and automatically free memory when the reference count reaches zero.

ARC automatically increments the reference count when a new reference to an object is created and decrements it when a reference is removed. When the count reaches zero, the object is removed from memory, helping to prevent memory leaks without the need for manual management.
