Optimizing Collections
Write custom collections in Swift with a strong focus on performance
by Károly Lőrentey
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.
