Textbook in PDF format

This version was published on 2023-06-28
The book about advanced Kotlin features most of us use, but nearly nobody understands, like variance modifiers, property delegation, interface delegation, contracts, multiplatform development, annotation processing, KSP, compiler plugins, and static analyzers. You can be a developer - even a good one - without understanding the topics explained in this book, but at some point, you’ll need it. You are likely using tools made using features described in this book every day, such as libraries based on annotation processing or compiler plugins, classes that use variance modifiers, functions with contracts, or property delegates, but do you understand these features ? Would you be able to implement similar tools yourself ? Would you be able to analyze and debug them ? This book will make all this possible for you. It focuses exclusively on the most advanced Kotlin topics, which are often not well understood even by senior Kotlin developers. It should equip you with the knowledge you need and show you possibilities you never before imagined. I hope you enjoy it as much as I enjoyed writing it
