What is the difference between 'assign' and 'retain' keyword?

Answer Posted / Pankaj Kumar Bhurji

'Assign' is a memory management strategy that creates a new object if the receiver is nil, or copies an existing object using a specified copying function. 'Retain', on the other hand, increases the retain count of an object by one, preventing it from being deallocated.
