Garbage collection is a type of programmed memory management in which memory, currently occupied by objects that will never be used again, is gathered. John McCarthy was the first person to come up with garbage collection for managing Lisp memory management. This technique specifies which objects need to be de-allocated, and then discharges the memory. The strategies that are utilized for garbage collection are stack allocation and region interference. Sockets, relational database handles, user window objects, and file resources are not overseen by garbage collectors.

Garbage collection algorithms help reduce dangling pointer defects, double-free defects, and memory leaks. These algorithms are computing-intensive and cause decreased or uneven performance. According to Apple, one of the reasons for iOS not having garbage collection is that garbage collection...
