Fetching a List of Episodes
Building a Modern Networking Layer in Swift
We start this series by making a simple GET request to the mock API to fetch the list of episodes. We won't be using a third party library. One of the goals of this series is to show you how to build a modern networking layer that relies on Foundation's URLSession API. It is simpler than you might think.

Exploring the API
Building a Modern Networking Layer in Swift
Most applications talk to a remote API in some way, shape, or form. Networking is therefore an important aspect of software development. Sending a request to a remote API isn't difficult, but there is more to it. In this series, you build a modern networking layer for a Swift application using Foundation's URLSession API. We cover a range of topics, basic and more advanced, from making a simple GET request to signing requests with an access token. We make use of generics and protocol-oriented programming to create a networking layer that is flexible, testable, and easy to extend.

Authenticating the User
Building a Sign In Form Using SwiftUI
With the view and the view model in place, we can authenticate the user. In this episode, you learn how to authenticate a user using the URLSession API and basic authentication.

Adopting the Model-View-ViewModel Pattern
Building a Sign In Form Using SwiftUI
In the previous episode, we built a sign in form using SwiftUI. In this episode, we create and integrate a view model that drives the sign in form.

Building the User Interface
Building a Sign In Form Using SwiftUI
In this series, we build a sign in form using SwiftUI. In the first episode, we build the user interface. In the next episodes, we apply the model-view-viewmodel pattern and perform a network request to sign the user in. At the end of this series, we have a fully functional sign in form that is ready to be integrated into an application.

Working with Units and Measurements in SwiftUI
SwiftUI Essentials
A few years ago, Apple added a number of APIs to the Foundation framework to make it easier to work with units and measurements. The APIs are flexible and straightforward to use. As of this year, SwiftUI integrates with these APIs to make it trivial to display units and measurements. The SwiftUI APIs we discuss in this episode are available as of iOS 15, tvOS 15, macOS 12, and watchOS 8.

Customizing Views with Modifiers
SwiftUI Fundamentals
To customize a view in a UIKit or AppKit application, you update one or more of the view's properties. For example, to change the text color of a UILabel instance, you update the label's textColor property. That is an imperative approach to user interface development.

Working with Xcode Previews
SwiftUI Fundamentals
SwiftUI's declarative syntax makes it straightforward to describe the user interface you have in mind. The API is intuitive and the framework's learning curve is gentle. But Apple didn't stop there. SwiftUI is deeply integrated into Xcode, making it almost trivial to build user interfaces using SwiftUI.

What Is a View
SwiftUI Fundamentals
A view is the fundamental building block of your application's user interface. You already know that a view is a type that conforms to the View protocol. In this episode, we take a closer look at views and the View protocol.

Exploring a SwiftUI Application
SwiftUI Fundamentals
While it is possible to integrate SwiftUI into a UIKit or AppKit application, this series focuses on building applications that are built entirely using SwiftUI.

What Is SwiftUI
SwiftUI Fundamentals
SwiftUI is Apple's brand new framework for building user interfaces for iOS, tvOS, macOS, and watchOS. Apple introduced SwiftUI in 2019 and the framework has been evolving at a rapid pace ever since. Unlike UIKit and AppKit, SwiftUI is a cross-platform framework. With SwiftUI, Apple offers developers a solution for rapidly building applications. In this series, you learn everything you need to build applications using SwiftUI.

Transforming Publishers with Flat Map
Building Reactive Applications With Combine
The API the image service exposes no longer accepts a completion handler. It returns a publisher instead. This is an improvement, but the image service still uses completion handlers under the hood. In this episode, we replace the completion handlers the image service uses internally with publishers.
