NSFetchRequest

An NSFetchRequest is like a query tool used in programming to retrieve specific data from a database. Think of it as a way to ask for certain records—such as all contacts from a contact list or all orders from a store—by specifying criteria. It helps software efficiently find and fetch only the relevant information needed for an app to display or process. This approach makes data management organized, fast, and effective, especially when dealing with large amounts of information stored inside an app.
