Overview of this book

Do you want to understand all the facets of iOS programming and build complex iOS apps? Then you have come to the right place. This problem-solution guide will help you to eliminate expensive learning curves and focus on specific issues to make you proficient at tasks and the speed-up time involved. Beginning with some advanced UI components such as Stack Views and UICollectionView, you will gradually move on to building an interface efficiently. You will work through adding gesture recognizer and touch elements on table cells for custom actions. You will work with the Photos framework to access and manipulate photos. You will then prepare your app for multitasking and write responsive and highly efficient apps. Next, you will integrate maps and core location services while making your app more secure through various encryption methods. Finally, you will dive deep into the advanced techniques of implementing notifications while working with memory management and optimizing the performance of your apps. By the end of the book, you will master most of the latest iOS 10 frameworks.

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.
