Lesson 1: Simple Persistence
In this lesson, you’ll learn about simple persistence and how to save small pieces of data, like user preferences, using NSUserDefaults.
Lesson 2: The iOS File System
In this lesson, we’ll discuss the iOS File System, the "sandbox", and how to access these files using NSFileManager.
Lesson 3: Comprehensive Persistence: Core Data (Part 1)
IIn this lesson, you’ll be introduced to the Core Data framework, Apple’s favorite framework for the model class. We’ll learn about the Core Data stack, how to create a model and managed model objects, and begin work on our very own note-taking app.
Lesson 4: Comprehensive Persistence: Core Data (Part 2)
In this lesson, we’ll continue our implementation of Core Data and learn how tableviews adjust their display, how a user can add new notes to the app, how we actually save and persist changes, and the important role Core Data plays in memory management.
Lesson 5: Important Extras
In this lesson, we’ll wrap up Core Data and discuss some important aspects of maintaining a persistent app.
Lesson 6: Core Data & Concurrency
Some tasks in Core Data can take pretty long, especially if your data model is complex or have a huge amount of data. Back in the Grand Central Dispatch course, we've seen how to send lengthy tasks to a background queue. In this lesson, we'll learn how Core Data tasks can run in different queues in a safe and efficient way.
