Objective-C : Memory leak

The application allows incorrect work with memory. Some errors related to memory management: no release of allocated memory (memory leak), double memory allocation, the use of the wrong class to free memory.

Objective C language is based on C and involves working with memory at a relatively low level. The developer must allocate memory for the structures used and release it correctly after the end of the work. Otherwise, memory available for the application will decrease, eventually causing malfunction of the application.
