Swift Data Structure and Algorithms

Overview of this book

Apple’s Swift language has expressive features that are familiar to those working with modern functional languages, but also provides backward support for Objective-C and Apple’s legacy frameworks. These features are attracting many new developers to start creating applications for OS X and iOS using Swift. Designing an application to scale while processing large amounts of data or provide fast and efficient searching can be complex, especially running on mobile devices with limited memory and bandwidth. Learning about best practices and knowing how to select the best data structure and algorithm in Swift is crucial to the success of your application and will help ensure your application is a success. That’s what this book will teach you. Starting at the beginning, this book will cover the basic data structures and Swift types, and introduce asymptotic analysis. You’ll learn about the standard library collections and bridging between Swift and Objective-C collections. You will see how to implement advanced data structures, sort algorithms, work with trees, advanced searching methods, use graphs, and performance and algorithm efficiency. You’ll also see how to choose the perfect algorithm for your problem.

Summary


In this chapter, we've learned about the difference between classes and structures and when you would use one type rather than another, as well as the characteristics of value types and reference types and how each type is allocated at runtime. We went into some of the implementation details for the array, dictionary, and set collection types that are implemented in the Swift standard library. And while not actually a collection type, we also discussed tuples and the two different types Swift supports.

We discussed how Swift interoperates with Objective-C and the C system libraries, and how Swift has added a feature called failable initialization so it can provide backward compatibility with Objective-C. Then we discussed some of the differences in how you call methods in Swift versus sending a message to an Objective-C receiver, as well as the different types of dispatching methods Swift supports. We saw how Swift supports bridging between the native Swift and Objective-C types and...
