iOS 17 Data Flow with Observation Framework

In this video I am going to be introducing you to the new Observation Framework that was introduced at WWDC23. The observation framework uses a new Observable macro that replaces the ObservableObject protocol and the @Pubished property wrappers. I will start back at the beginning to go over the @State and @Binding property wrappers that are applied to simple Value types in your views then go through how @StateObject is now replaced with the simple @State for objects and how @ObservedObject is now replaced with an @Bindable attribute I will finish by showing you want is required now to add object that is marked as Observable into the Environment, replacing the olde EnvironmentObject propertyWrapper with the old Environment If you want to support my work, you can buy me a coffee :) https://ko-fi.com/stewartlynch Table of Contents: 0:00 Introduction 1:54 The Basics @State and @Binding 6:01 Observation Framework and @Observable macro 12:25 @State and @Bindable 18:31 @Environment and @Bindable Starter Project Files: (If you are having problems downloading zip files, use Safari.
