Do you use strong or weak references when working with array elements in your project?

In Swift, when working with arrays, strong references are usually used because arrays are structures (value types) that are copied upon assignment.

However, if the array contains classes (reference types), then strong references to objects are stored inside the array. This can lead to cyclic references if objects refer to each other.

To avoid memory leaks, in such cases, weak or unowned references are used, but in arrays, this cannot be done directly because weak references must be optional and cannot be stored directly in arrays.

To work around this, wrappers are used, for example:

class Wrapper {
    weak var value: SomeClass?
    init(value: SomeClass) {
        self.value = value
    }
}

var array: [Wrapper] = []

Thus, in regular arrays, strong references are used, and weak references are applied through wrappers if needed to avoid retain cycles.
