Course content

11 sections • 51 lectures • 8h 13m total length

Course Outline and Goals2:21
FAQ1:16

Section Goal1:22
Note for Xcode 10 Storyboarding0:05
CoreData Project8:45
On this first app, we are going to build the app from scratch to get the basic idea how to setup a Core Data project from the beginning. This would be the only time we will be building from a new project. On subsequent app, you can start following along using a starter project and we will jump right into a Core Data topic.
Keystone Park UI13:46
We will start laying out the UI for Keystone Park app by storyboarding.
CREATE New Data 118:29
In the first part of CREATE data lecture, we are going to build the service layer that will allow us to enter student and lesson information to Core Data. We will jump into the concept entity and predicate including how to start querying the Core Data based on the search criteria.
CREATE New Data 213:48
We are going start utilizing the service layer to insert new student and lesson record to Core Data.
READ Current Data12:09
We will use search criteria to send request to Core Data and display the data in our tableView. This would be the READ part of the CRUD functionality we are building in this Keystone Park app.
UPDATE Existing Data19:43
We will build the service layer to update the existing record. This would be the UPDATE part of the CRUD functionality.
DELETE Existing Data8:16
We are exploring the DELETE functionality of the CRUD and learn how to properly delete record within entities relationships.

Section Goal0:13
Extract CoreData Boiler Plate5:55
We are going to take a quick look how extract the Core Data boiler plate out of AppDelegate to create a cleaner CoreData stack.
Source Codes0:19
Extract JSON Data13:16
We will look into parsing a json format data and store the extracted information into the Core Data with sqlite backend.
Fetching Data with NSFetchedResultsController5:36
We are going to learn how to fetch data and store the results in NSFetchedResultsController.
TableView Datasource14:02
We will learn how to populate tableView section and row by utilizing the NSFetchedResultsController coming from the service layer.
Data Update and Refresh19:21
Learn the strategy on how to properly update a single record and refresh the UI using NSFetchedResultsController to reflect the changes immediately to the users.
Batch Update11:03
Learn how to run a batch update to modify a set of records and properly refresh the UI.
Data Removal8:50
We will use NSFetchedResultsController to properly handle record deletion in a tableView.
Group and Cache5:56
Check this lecture to see how easy doing a grouping of data using NSFetchedResultsController. We will also explore how to take advantage of data caching which can bring benefits if you are dealing with a large set of data.

Source Codes0:18

Entity Inheritance5:25

We will learn how to setup an inheritance relationships for the entities in the data model which will translate to NSManagedObject inheritance setup.

Extract Data for Inheritance31:37

We will extract the JSON data and uploading the record to Core Data based on the entity inheritance that we setup in the data model.

Entity Extension12:12

We are going to create an extension to our NSManagedObject class that will provide a service to our data model during data reading and manipulation.

Entity Relationships as Predicate18:48

Explore how we can take advantage of entities relationships in fetching Core Data records.

Filter and Sort13:33

Learn how to setup multiple predicates and sort that can be used as search criteria.

Compound Predicate and Multi Sort12:27

We will learn into using multiple predicates and sort mechanism to query the Core Data entities and relationships.

Aggregate Function - 119:58

Aggregate Function - 213:37

Section Overview9:46
In this section we will demonstrate how managing different managedObjectContexts may affect the performance of your app and provide a better user experience.
Background Context12:57
We will explore the private background context and see how it can provide a better user experience.
Asynchronous Execution4:21
We will look into another alternative of managing the managedObjectContext without using a separate background context.

Section Goal0:30
Dealing with Large Images14:55
This lecture will introduce us to Xcode Memory Debugging and Core Data Profiler. We will inspect the application memory footprint and how the different approach of Core Data implementation can impact the performance of our application. We will look into how to efficiently deal with large images and how to use thumbnail when necessary will bring performance impact to the application.
Fetch Data by Batch Size5:20
We are going to implement batch size fetching to limit the number of records requested from Core Data store to improve the application performance. It is on demand fetching.
Measuring Performance27:59
We are going to implement different fetching strategy to improve our application performance. We will be using unit testing to compare the application performance on before and after tuning up our codes.

Section Overview0:28
Light Weight Migration10:15
We will first look into a simple migration process that will involve a single entity.
Data Migration with Mapping Model - 118:27
In this lecture we will learn a more complex data migration that will involve multiple entities and how to migrate existing data from an existing entity into new entities.
Data Migration with Mapping Model - 227:44
We will finish up the complex data migration process by updating the references to previous and new entities.

CoreData for iOS Development in Swift

This course was created and updated for Core Data with the latest Swift 4.x (as of WWDC 2018), targeted for both iOS 12 and 11. We will be using the latest Xcode 10 (Beta) as well as Xcode 9.4 for the course coverage.

If your project is dealing with older version of Core Data in iOS 9 or prior, and you intend to learn the previous version, my other course Mastering iOS Core Data with Swift is the course you want.

What is Core Data? Why should I know about Core Data?

Core Data is one of the most powerful framework that Apple has provided for developer. "Core Data is a framework that you use to manage the model layer objects in your application. It provides generalized and automated solutions to common tasks associated with object life cycle and object graph management, including persistence." - Source from Apple".

If you are passionate about learning mobile development for iOS and looking to take your iOS development skills to the next level, Core Data framework should be at the top of your list.

By the time you are done with CoreData for iOS Development in Swift course, you will be ready and very confident to take on any Core Data project coming your way. On top of that, you will be one step closer to become a well rounded iOS developer.

What's in it for me?

In this course I will take you on a journey in the world of Core Data. We will cover all the important aspects of Core Data:

Entity
Entity Inheritance
Attribute Type
Relationships
ManagedObjectContext
ManagedObject
PersistentContainer
Handling JSON data
Predicate
CompoundPredicate
Fetching
Batch Fetching and Update
Object Deletion
Asynchronous Fetching
NSFetchedResultsController
Aggregate Functions
Grouping
Caching
Performance Tuning and Best Practices
Data Model Versioning
Automatic Lightweight Migration
Manual Migration with Model Mapping
Background process
Automatic Subclass and Class Extension Generation

Throughout this course we will look in detail the Core Data framework to provide data storage functionality in iOS applications. We will start by creating a simple app that is utilizing Core Data framework, building our own Core Data stack and eventually using all different Core Data features into our application.

Performance Tuning and Best Practices

We will cover the various ways on fetching our data and how to efficiently using Core Data in our app. Unit testing and performance tuning will be an important part on how we can monitor our app performance in conjunction with Core Data in our application.

Along with Core Data versioning, migration and iCloud integration, I will take you on developing 5 iOS applications and how we can integrate all of these components into Core Data.

Do at your own pace

Lots of students have different methods of learning. Through out this course I will provide both the starter and final Xcode project solution, so you can either follow along one step at a time or you can jump directly to the final solution. And by the end of this Core Data for Swift Development course, you should be comfortable and ready to integrate Core Data framework in your application.

Target Audience: All iOS developer that would like to take their skills to the next level.
