Who this book is for 

Swift Data Structures and Algorithms is intended for developers who want to learn how to implement and use common data structures and algorithms natively in Swift. Whether you are a self-taught developer without a formal technical background or you have a degree in Computer Science, this book will provide with the knowledge you need to develop advanced data structures and algorithms in Swift using the latest language features. An emphasis is placed on resource usage to ensure the code will run on a range of platforms from mobile to server. A previous background in an object-oriented language is helpful, but not required, as each concept starts with a basic introductory.
