Hello Guys,
Do you want to learn about the Type Casting in iOS here we go...
Type casting is a way to check the type of an instance, or to treat that instance as a different superclass or subclass from somewhere else in its own class hierarchy.
Type casting in Swift is implemented with the is and as operators. These two operators provide a simple and expressive way to check the type of a value or cast a value to a different type.
You can also use type casting to check whether a type conforms to a protocol, as described in Checking for Protocol Conformance.
Thanks
