Preface

Introduction


Concurrency is always considered a nightmare for many developers. I partially agree with these developers and think that concurrency is a big headache if you don't understand it well and don't know how to use it. In this chapter, we will try to get your hands dirty working with concurrency. We will understand what's going on and see how simple it is with the APIs that iOS provides, to work with it and harness its capabilities. Concurrency is a two-sided weapon; it can be helpful and harmful at the same time. It helps you to write efficient, fast executing, and responsive apps, but at the same time, misusing it will ruin your app memory. That's why, before starting to write any concurrency code, think why you need concurrency and which API you need to use to solve this problem? In iOS, we have different APIs that can be used. In this chapter, we will talk about two of the most commonly used APIs: Operation and Dispatch queues.
