In this lesson, you will download URLs for images using the Flickr API and Alamofire.

In this lesson, you will download images and populate an array with images using the Flickr API and AlamofireImage.

In this lesson, you will set up UICollectionView to create cells with images using imagesArray. You will also reload the data of the UICollectionView so that it shows all images once they’ve finished downloading.

In this lesson, you will build PopVC which is a UIViewController that will display images. You will also set up UICollectionView to present PopVC whenever a cell is tapped.

In this lesson, you will add 3D Touch functionality to UICollectionView. When you press lightly on a cell, you will be able to Peek at the content. A firmer press will Pop it onto the next UIViewController.

In this video, you will be introduced to GoalPost – the Core Data goal setting app you'll be building in this section.

In this lesson, you will create the Xcode project used to build GoalPost. You will also set up project folders for organizational purposes.

In this lesson, you will build GoalsVC in Interface Builder. This is the home screen of GoalPost.

In this lesson, you will build GoalCell in Interface Builder and also create the code subclass to go with it.

In this lesson, you will create the Core Data entity called Goal. You will also set up several attributes for that entity. Think of this like a model class and it's properties.

In this lesson, you will configure some static instances of GoalCell in order to confirm that out UITableView is working properly.

In this lesson, you will build out CreateGoalVC in Interface Builder. This ViewController is where the user describes their goal and sets it type.

In this lesson, you will create an extension of UIViewController that will allow you to customize the presentation of UIViewController instances. You will cause the animation to resemble a UINavigationController animation.

In this lesson, you will create an extension of both UIView and UIButton which will help with various UI enhancements.

In this lesson, you will build out FinishGoalVC in Interface Builder and pass data to it from CreateGoalVC.

In this lesson, you will write a function to save data to the Persistent Store using Core Data. You will save data from FinishGoalVC into the Persistent Store.

In this lesson, you will write another function in the UIViewController extension that will allow for the proper dismissal of FinishGoalVC. It will dismiss the current UIViewController and present the other simultaneously to avoid a stack of too many ViewControllers.

In this lesson, you will fetch data from the Persistent Store by using an NSFetchRequest. You will save the results in an array of Goal and display it in the UITableView.

In the lesson, you will write a function to remove an object from the Persistent Store using a UITableViewRowAction set up for deletion.

In this lesson, you will write a function to update the goalProgess attribute of the Goal entity. You will enable the UITableViewCells for goals to be updated with a UITableViewRowAction set to update the goalProgress attribute.

In this video, you will be given a challenge to extend GoalPost and add an undo feature.

In this video, you will be introduced to Breakpoint – the coder-centric social media app you will be building in this section. It features a public feed, group messaging, and a real-time Firebase backend.

In this lesson, you will create the Xcode project for Breakpoint and set up some organizational folders for the Model, View, and Controller layers as well as folders for Extensions and Services.

In this video, you will create a new project in the Firebase Console. Then, you will download a .plist file containing valuable Firebase data. You will install the Firebase CocoaPods to give our Xcode project the ability to communicate with Firebase.

In this lesson, you will create a singleton class called DataService which will allow you to interface with our Firebase Database. You will write a function allowing you to create users and add them to the Database as well.

In this lesson, you will build out AuthVC and LoginVC in Interface Builder.

In this lesson, you will create the InsetTextField and ShadowView subclasses which you will use to set custom appearance for several UI elements in AuthVC and LoginVC.

In this lesson, you will write AuthService – a singleton class responsible for registering and logging in users to Firebase.

In this lesson, you will build FeedVC and GroupsVC in Interface Builder.

In this lesson, you will set up the AppDelegate to monitor for changes to the currently authenticated user and present LoginVC if the user is ever logged out. You will also authenticate users with their email and upload them to Firebase.
