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.
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.
Handling errors is one of the less enjoyable aspects of software development, but it is an important one. You don’t want to show the user a cryptic error message when something goes wrong, or worse, no error message. There is no clear-cut recipe you can follow. Every project is different. The good news is that error handling is built into Swift and the Combine framework. Let me show you how we can improve the code we wrote in the previous episode.
