iOS Swift - Local Data Persistence

Given the following SwiftData code snippet, what will be the output?

let newBook = Book(title: "Swift Basics")
context.insert(newBook)
let books = try context.fetch(Book.fetchRequest())
print(books.count)

A0

BError: fetchRequest not found

C1

Dnil

Step-by-Step Solution

Solution:

Step 1: Insert newBook into context
The code inserts one Book instance into the context, so one object is stored.
Step 2: Fetch all Book objects and count
Fetching returns all stored Book objects, which includes the one just inserted, so count is 1.
Final Answer:
1 -> Option C
Quick Check:
Inserted one object, fetch count = 1 [OK]

Quick Trick: Inserted objects appear in fetch count [OK]
