How does object management within an array occur in the context of capturing them into another structure or lambda function?

In iOS, when working with arrays of objects and capturing them in another structure or lambda function (e.g., closure), it is important to understand memory management and object ownership.

• If the objects in the array are classes (reference types), capturing in a closure involves capturing a reference to the object. This does not copy the object but retains a reference, which can lead to cyclic references if the closure retains the object and the object retains the closure.
• To avoid leaks, weak (weak) or unowned (unowned) references are used inside closures.

Example:

class MyObject {
    var value: Int
    init(value: Int) { self.value = value }
}

let array = [MyObject(value: 1), MyObject(value: 2)]

let closure = { [weak array] in
    guard let array = array else { return }
    for obj in array {
        print(obj.value)
    }
}

closure()

If objects are structs (value types), then capturing involves copying the values.

Thus, object management during capture depends on the type (class or struct) and how they are captured in closures.
