Answer Posted / Rashmi Banival
In iOS, 'strong' and 'weak' are memory management concepts used primarily with Objective-C. They help to manage the lifecycle of objects. Strong references increase the retain count of an object by one, preventing it from being deallocated until that strong reference is released. Weak references do not increase the retain count of an object and allow it to be deallocated when its last strong reference is released. An example of weak reference is using a delegate or a notification observer.
