WeakRef

The WeakRef in Swift provides a mechanism to hold a weak reference to objects, particularly useful when you want to reference an object without preventing the Automatic Reference Counting (ARC) system from disposing of it.

Features

• The primary purpose of the WeakRef structure is to allow weak referencing to an object of type T, where T is any class type.
• Easily check if the weak reference holds a valid object or if it has been nilled out with the isEmpty and isValid computed properties.
• Equatable conformance allows weak references to be compared for equality with other weak references or directly with any object. Hashable conformance ensures you can store WeakRef in sets or use them as dictionary keys.
