How does memory release occur for value types stored on the stack?

Value types in Swift, such as structures and enumerations, are stored on the stack. Memory for them is automatically released when they go out of scope, where they were created. This is because the stack operates on a LIFO (Last In, First Out) principle: when a function or block of code finishes, all memory allocated for local value types is automatically freed.

Therefore, programmers do not need to explicitly manage memory for value types on the stack — the system handles it automatically, reducing the likelihood of memory leaks.
