Can you explain how management of different stages of an object's existence occurs in programming?

Object lifecycle management in programming refers to controlling its creation, usage, and destruction. Different languages and platforms implement this in various ways, but the general idea is to ensure proper allocation and release of resources.

For example, in iOS and Swift:

• Initialization: the object is created through constructors (init), where necessary resources are allocated.
• Usage: the object performs its functions and may change its state.
• Deallocation: when the object is no longer needed, the memory management system (ARC — Automatic Reference Counting) automatically releases memory by calling deinit.

Example:

class MyObject {
    init() {
        print("Object created")
    }
    deinit {
        print("Object destroyed")
    }
}

func createObject() {
    let obj = MyObject()
    // use obj
} // after exiting the function, obj is destroyed

Thus, lifecycle management helps prevent memory leaks and ensures stable application operation.
