Optimizing Collections

Write custom collections in Swift with a strong focus on performance

by

In this book, we show how to write very efficient Swift collection code. Throughout the book, we benchmark everything — with some surprising results. We implement custom data structures with value semantics and copy-on-write behavior such as sorted arrays, binary trees, red-black trees, and B-trees.

Even if you never implement your own collections, this book helps you reason about the performance of Swift code.

Update Notice — We’ll be updating the book for Swift 4.0 later this year. If you buy the Ebook now, or have bought it in the past, you’ll get the update for free when it’s available.
