What is method swizzling in objective c and why would you use it?..

Answer / Sudha Maurya

"Method Swizzling" is a technique used in Objective-C to dynamically swap out implementation of methods at runtime. It's useful when you want to modify the behavior of existing classes without modifying their source code or creating subclasses. This can be particularly helpful for debugging, testing, or implementing libraries.
