Data Persistence in iOS: Core Data, SQLite, and UserDefaults Training Course

Rating

9/10

Duration

3 Days

Course Overview

This course provides a comprehensive understanding of data persistence in iOS applications, covering Core Data, SQLite, and UserDefaults. Participants will learn how to store, retrieve, and manage data efficiently, whether for simple user preferences or complex relational databases. The course includes hands-on exercises to implement Core Data entities, perform CRUD operations in SQLite, and manage lightweight storage with UserDefaults.

Format of Training

  • Instructor-led sessions
  • Hands-on lab exercises
  • Interactive discussions
  • Practical coding demonstrations
