12 sections • 42 lectures • 4h 38m total length

Introduction3:49
In this lecture Mohammad Azam is going to explain the agenda for the complete course.
What is Massive View Controllers?1:16
In this lecture students are going to learn what exactly is "Massive Controller". We are going to see some basic principles of programming which massive controllers break.
What is a Lean Controller?1:37
In this lecture students will learn the concepts behind "Lean Controllers". Through the use of diagrams students will learn how to structure their application to utilize the concepts of lean controllers.

Designing Wireframes Using Keynote7:19
Before diving into Xcode we will create a very simple prototype of our application using Keynote. You can use any prototyping tool for this lecture.
Implementing User Interface in Storyboard6:51
In this lecture we will use our prototype to create the interface in Xcode using Storyboards.
Integrating with Core Data6:27
In this lecture we will integrate our view controller with Core Data. We will write all of our code write inside the view controller to represent the massive view controller. Later we will use the principles of lean controllers to rearrange our code and break it into smaller components.
Creating Custom View to Add New Shopping List6:18
In this lecture students will learn how to create the custom view for the table view header. This view will not be reusable. We will later learn how to create a reusable view which can be easily used in many different applications.

Saving New Records6:15
In this lecture students are going to learn how to save data into SQLite database using Core Data.
Fetching Records and Displaying them in UITableView12:11
In this lecture students are going to learn how to fetch records from the SQLite database using NSFetchedResultsController class.
Deleting Records6:04
In this lecture students are going to learn how to delete records from the SQLite database using the NSManagedObjectContext.

Recap of the Grocery App3:53
In this lecture we will look at the mess we have created in our view controller. This is known as massive view controller and it is not pretty to look at.
Implementing Core Data Manager8:55
In this lecture students are going to learn how to move all the Core Data initializer code into a separate Core Data Manager class. Core Data Manager class will encapsulate all the different methods and properties associated with Core Data.
Implementing Shopping List Data Providers13:15
In this lecture students will learn how to move all the code responsible for fetching data into a separate class. This will remove the view controller's dependency from the NSFetchedResultsController and the NSFetchedResultsControllerDelegate.

Implementing Shopping List Data Sources11:28
In this lecture students are going to learn how to separate the UITableViewDataSource from the UITableViewControllers. This lecture is going to dive into creating a concrete data source which can be used by the ShoppingList model.
Communicating Between Data Provider and Data Source8:20
In this lecture we will expose protocols from our data providers which will be consumed by the data source. This will allow data to flow from data providers to data sources.
Deleting Shopping Lists Using Data Source and Provider8:15
In this lecture students will learn not only how to delete the data from the database using the providers but also how to remove the row from the table view control.

What's Wrong with the Current Approach2:54
This lecture explains what is wrong with the current approach of creating the user control right inside our table view controller.
Creating a Custom Add New Item Control5:56
Students are going to learn how to create a custom add new item control which can be utilized by any view controller.
Adding Custom Initializer to Configure Place Holder Text3:57
In this lecture we will configure the custom control so it can be used to display any place holder text.
Passing Data from AddNewItemView Using Delegates8:14
The AddNewItemView control is useless if it cannot communicate with the view controller. In this lecture we will learn how our custom control can communicate with the view controller through the use of Delegates and Protocols.
Passing Data from AddNewItemView Using Closures7:23
In this lecture students will learn a second way of passing data from the user control to the view controller in the form of closures.

What's Wrong with the Current Approach4:13
In this lecture student will learn what is wrong with our approach of implementing concrete data providers and data sources.
Creating a Generic Data Provider17:38
In this lecture students are going to start building a generic data provider class which can be used for any type of model.
Implementing a Generic TableView Data Source Part 112:03
In this lecture students will learn how to get started with creating a generic data source which can be used to work for any table view controller, table view cell and entity model.
Implementing a Generic TableView Data Source Part 26:25
We will continue working on our custom generic data source class for table view.
Saving Records Using Generic Providers and Data Sources7:49
In this lecture students are going to learn how to persist records and delete records using generic providers and data source classes.

Understanding the Scenario7:09
In this lecture, Mohammad Azam will explain the scenario of creating a separate layer for web service actions.
Developing a Webservice Class8:41
In this lecture, Mohammad Azam will demonstrate how to create a Webservice class which is responsible for all networking operations.
Refactoring Webservice Class3:07
In this lecture, Mohammad Azam will refactor the existing Webservice and Model classes to make it more seamless.
