The Mystery of the Mutating Mannequin: An Exploration of Data Flow in SwiftUI

The Mystery of the Mutating Mannequin is a fun, fast-moving tour of the different techniques of flowing data through your SwiftUI app.

We start with the simplest of views that contains no state to those that use simple properties, @State properties, or share state using @Binding. Throughout this journey through things you thought you knew, we use various tools to see which views are redrawn when and why.

Next, we manage and persist an object graph manually or go old school with Core Data on your way to learning about the future when we work with SwiftData.

Now available from pragprog.com/titles/d-dsflow.

This work was written and produced entirely by the author. We are proud to be distributing it.
