Populating the Feed: Creating the API Client
From Zero to App Store
We successfully fetched a list of episodes from the Cocoacasts API and converted the data into model objects. The code we wrote works, but it is far from finished. In this episode, we create a dedicated object that manages the communication with the Cocoacasts API.

Populating the Feed: Prototyping in a Playground
From Zero to App Store
The first episodes of this series have almost exclusively focused on creating a foundation for the project. While this may seem tedious or even premature, it allows anyone working on the project to focus on writing code. Automation is an important part of modern software development and it pays to set aside some time to create a foundation for the project you're working on.

Protecting the Secrets of Your Mobile Application
Swift and Cocoa Essentials
I tend to talk about topics that aren't very exciting to most developers, but I also try to make it a habit to discuss topics that are fundamental for software development. Security ticks both boxes. Few developers get excited when I bring up security. The truth is that security should always be top of mind when you are creating software.

Combining Observables With Operators
Building Reactive Applications With RxSwift
Operators are a key component of RxSwift and the ReactiveX API. They help make reactive programming powerful and flexible. In the previous episode, we explored operators that transform and filter the values emitted by an observable. This episode zooms in on operators that combine multiple observables into one observable. Combining observables is a common pattern and it can greatly simplify the implementation of a range of tedious tasks.

Transforming and Filtering Observables With Operators
Building Reactive Applications With RxSwift
Operators are a key component of RxSwift and the ReactiveX API. RxSwift defines dozens of operators that create, filter, or transform the values emitted by observables. In this episode, I show you why operators are an integral component of RxSwift and we take a look at a few examples.

Observables, Observers, and Memory Management
Building Reactive Applications With RxSwift
This episode focuses on memory management. While memory management isn't the most exciting subject, it is one of the most important subjects of this series. Most developers new to RxSwift struggle with memory management. It isn't hard, but you need to learn and understand the basics.

What Is an Observable Sequence
Building Reactive Applications With RxSwift
The fundamental building block of RxSwift is the observable sequence. Synonyms of observable sequence are observable, sequence, or data stream. In the rest of this series, we refer to observable sequences as observables.

Installing RxSwift and RxCocoa
Building Reactive Applications With RxSwift
There are several options for integrating RxSwift into a project, including CocoaPods, Carthage, and the Swift Package Manager. In this series, we use CocoaPods. You can find installation instructions for Carthage and the Swift Package Manager on GitHub.

ReactiveX, RxSwift, and RxCocoa
Building Reactive Applications With RxSwift
Swift isn't a reactive programming language so we need a bit of help to make it reactive. A handful of libraries and frameworks are available to build reactive applications. The most commonly used solutions are RxSwift, ReactiveCocoa, and Apple's Combine framework. RxSwift is by far the most commonly used library at the time of recording.

What Is Asynchronous Programming
Swift and Cocoa Essentials
Many developers still get confused when they come across the word asynchronous. What does it mean? What is asynchronous programming? To understand what asynchronous programming is, we first need to understand its counterpart, synchronous programming. Let's use a playground to illustrate the difference.

What Is Reactive Programming
Building Reactive Applications With RxSwift
Building Reactive Applications With RxSwift is a practical introduction to reactive programming. Reactive programming asks for a new mindset. You need to think differently and that may take a bit of time. Reactive programming changes how you think about code and that is what trips up many developers that are new to reactive programming.

Choosing Between Closures and Delegation
Mastering Navigation With Coordinators
There are several options for sending messages from a view controller to its coordinator. Up until now we exclusively used closures to notify the coordinator. Another option is delegation and that's the pattern we explore in this episode.
