What Is Auto Layout
Auto Layout Fundamentals
Before I discuss the benefits of Auto Layout, I'd like to take a moment to discuss the options you have for creating user interfaces on iOS. Every view in the view hierarchy of a user interface needs to have a size and a position.

Welcome to Auto Layout Fundamentals
Auto Layout Fundamentals
Welcome to Auto Layout Fundamentals. In this series, you'll learn about the fundamental concepts that power Auto Layout. At the end of this series, you'll have a solid understanding of Auto Layout and how you can use it in your projects.

Where to Go From Here
Core Data Fundamentals
My hope is that this series has taught you that Core Data isn't as difficult as many developers believe it to be. Core Data isn't complex once you understand how the various pieces of the framework fit together.

Understanding Faulting
Core Data Fundamentals
In this episode, I'd like to discuss a concept that often confuses developers new to Core Data, faulting. Before I explain what faulting is, I want to show it to you.

Replacing the Core Data Manager Class
Core Data Fundamentals
The CoreDataManager class is in charge of the Core Data stack of the application. It encapsulates the Core Data stack and only exposes the main managed object context to the rest of the application.

Using a Better Core Data Stack
Core Data Fundamentals
Because we updated the CoreDataManager class in the previous episode, we need to make a few changes in the project.

Updating the Core Data Manager for Concurrency
Core Data Fundamentals
It's time to refactor the CoreDataManager class. Let me walk you through the changes we need to make. Don't worry, though, most of the implementation of the CoreDataManager class remains unchanged.

Working In a Multithreaded Environment
Core Data Fundamentals
We currently use one managed object context, which we created in the CoreDataManager class. In the application, we pass the managed object context to the objects that need it. This works fine, but there will be times when one managed object context won't cut it.

Assigning Tags to a Note
Core Data Fundamentals
The last feature I want to add is the ability to tag notes. This feature is interesting because of the Many-To-Many relationship of the Note and Tag entities. In this episode, you learn how to work with such a relationship.

Versioning the Data Model
Core Data Fundamentals
In the previous episode, we exposed the root cause of the crash we ran into earlier. The solution is versioning the data model.

Data Model Migrations
Core Data Fundamentals
An application that grows and gains features also gains new requirements. The data model, for example, grows and changes. Core Data handles changes pretty well as long as you play by the rules of the framework.

Adding a Dash of Color
Core Data Fundamentals
In this episode, I'd like to add the ability to assign a color to a category. This makes it easier to visualize which category a note belongs to.
