Creating Multi-Process Mac Applications
Creating Multi-Process Mac Applications
Exploring clean ways to split an app into concurrent processes, share data, and not break anything.
About the Book
LIMITED BETA PRICING: only $5.99!
Learn how to make your app more resilient, failure-proof, and modular.
This book will teach you how to create Mac applications which utilize background processes for heavy lifting and use the main application for the user interface only.
Set up your project with a daemon–client separation in mind and share data effortlessly. You will learn about the various ways of Inter-Process Communication on the Mac and how to use the modern Cocoa XPC in particular.
Build enterprise-level applications: they are easy to scale and ready for features. They become resilient to changes by splitting concerns between processes. This will help you think of your application as a suite of simpler services which can grow independently and thus more easily.
After Exploring Mac App Development Strategies introduced basics of software architecture to the communicty, this book will utilize the guiding principles to create a complex real-world application.
