Answer 1

NSClassFromString() is a function that returns an Objective-C class. That is, in Objective-C a class is an honourable object. An instance of the "Class" class...

And what is an Objective-C class good for?

for instantiating objects (via alloc init ) for introspection and reflection - to query it for the methods and properties instances of that class are exposed to the user for archiving/de-archiving instances of that class, and... to be able to run class methods (methods that do not require any specific instance of that class.

your last lines actually create an instance of the class whose name is the string passed to NSClassFromString.
