They are not really comparable.

UIView is the programming object, that contains all the methods and properties the application communicates with display a view.

An XIB is a graphic representation and holder file, that contains the definition for the graphical look of the application (in one context).

An XIB really can't exist without a UIView to communicate with it.
A UIView can exist without an XIB as all the objects can be done via code.

This is an extremely simplistic comparison to answer your question.
I am sure others will pipe in with more information.
