In this chapter, we saw how to apply updation and a searching facility to the customer's information. We saw the usage of NSPredicate in applying filtering conditions to the entity instances and hence displaying only the customer names that match with the characters typed in the Search Bar control.
In the next chapter, we will learn how to add one more entity:
Product to our application that will be used for storing information to the different products sold to the customers. We will also learn how to set a relationship between the Customer and Product entities in that chapter.
