Mastering Core Data With Swift
“I want to learn Core Data,
Every Swift Developer
but I don’t know where to start.”
“I was frustrated with Core Data until I took the time to learn the fundamentals.”Yours Truly
“Core Data is difficult to use.”I Prefer to Stay Anonymous
“I don’t have the time to learn the framework.”I Use a Core Data Library as a Shortcut
“Core Data is verbose and has a terrible API.”I've Never Tried to Use Core Data
The first time I came into contact with Core Data was more than ten years ago. I was immediately overwhelmed by the terminology, the complex setup, and the many rules I had to stick to.
Does this sound familiar? I wondered if it was worth the hassle? And why did experienced developers swear by Core Data? How was I going to master Core Data and integrate it into an application without running into mysterious crashes?
The Solution Was Surprisingly Simple
Whenever I teach developers Core Data, I emphasize how important it is to focus on the fundamentals first. The vast majority of issues developers run into are caused by a lack of knowledge about the ins and outs of the framework. Core Data isn’t difficult if you understand how the framework works.
A Proven Roadmap to Master Core Data
Over the years, I’ve taught thousands of developers how to use Core Data. This has taught me what the common pitfalls are developers run into. In Mastering Core Data With Swift 3, I show you the pitfalls you need to avoid.
The video course follows a proven roadmap that starts with the fundamentals of the framework. We cover some theory, but, more importantly, you immediately apply what you learn to build a real application. Practice makes perfect. Right? This very much applies to any programming subject.
Ready for Xcode 8 and Swift 3
In Mastering Core Data With Swift 3, you learn everything you need to know to integrate Core Data in a new or an existing Swift project. We focus on the key players of the framework and build an application that takes advantage of the core features of the framework.
We use the latest and greatest to build an application. Xcode 8 has many improvements that make working with Core Data fantastic. And the intuitive syntax of Swift 3 adds the cherry on the cake. It has never been easier to get started with Core Data.
Building a Real Application
We start the course with an exploration of the heart of every Core Data application, the Core Data stack. We then take a closer look at the data model of a Core Data application. You learn about entities, attributes, and relationships. These are the ingredients of every Core Data application.
During the course, we build an application that manages notes. We start from scratch, build a Core Data stack, create a data model, and add several features, such as categories and tags. Every feature teaches you a new concept of the Core Data framework.

… And Beyond the Basics
We don’t skip the more advanced features of the framework. We discuss data model migrations, working with multiple managed object contexts, and using Core Data in a multithreaded environment.
While some of these topics may seem advanced, they are essential for building a robust, scalable Core Data application. This is a common mistake developers new to Core Data make.
“When things hit the fan, I just don’t know what to do. I’ve never taken the time to learn the fundamentals of the framework.”
Even though I was already familiar with MVVM, Bart’s course showed me a different perspective on MVVM by refactoring a complete application built with MVC. He illustrates how MVVM can improve a project’s architecture and testability, and how reactive programming fits in.Damian Esteban
This is one of the finest Swift material available on the internet. Thank you.Rakesh Kusuma
It has been a pleasure to work with Bart. I’ve found him to be diligent, conscientious, and reliable. His own competence has made my job much easier. And his skill as an iOS developer continues to amaze me.Adam Brown
You made a daunting subject a lot more manageable.Kitson Broadhurst
A big thank you. This has been the single most effective course I've taken about iOS. I put it into practice right away and our App Store app, and its testing, has benefited greatly.Jake Young
This is by far the best explanation of Core Data I have read. After working on my first Core Data project for the last three days, I actually understand what you are saying here.Gravity Zero Design
Wow, I really love these tutorials. Great job. You are very good at explaining things from the ground up in a way that is both fast (not boring) and yet comprehensive.Jonas Nelle
Is This Course for you?
You Want to Learn Core Data
You already have experience building applications using Swift and Xcode. You are ready to step up your game and add Core Data to the mix.
You Are Frustrated With Free Tutorials
There are many tutorials and courses available. Most of them are out of date and many of them don’t teach how to correctly use Core Data in a modern Cocoa application. You want to learn Core Data once and be done with it.
You Have Tried Learning Core Data but It Hasn’t Clicked Yet
I’ve been there and I know exactly how it feels to hit that wall. I promise you that Core Data is not difficult. Mastering Core Data With Swift 3 shows you the path of least resistance. And don’t forget that I’m here to help you.
You Want to Learn From a Professional
There are hundreds of free tutorials and videos to learn Core Data. I’ve been using Core Data for more than ten years. I show you in less than three hours how to use and integrate Core Data in a modern application powered by Swift.

Who Am I?
My name is Bart Jacobs and I’m the founder of Code Foundry, a mobile development company. I’ve been teaching since 2004 and I currently focus primarily on teaching Swift developers how to create robust, scalable applications for Apple’s platforms using Swift and the Cocoa frameworks.
I’m crazy about film music and I have a soft spot for tea and coffee. I’m currently weaned off coffee, but we’ll see how long that lasts.
