Below you’ll find the different series of articles on overarching topics. If you want to deep dive into something, this is the place!
You don’t belong on the main thread, so best move as much of your off of it. In this series, we explore how to create asynchronous operations to create non-trivial interactions. You’ll learn how to chain them together in series and in parallel, as well as how to abstract away commonly used operations so you can keep your code clean. Finally, we dive into UIKit, and how we can integrate Apple-provided view controllers (like UIAlertController) and our own view controllers, into our operation chains.
