Скачать или смотреть Observable Objects in SwiftUI

In this video, I'm going to talk about Observable Objects in SwiftUI and why we require them additionally to @state properties. Let's explore two common usages for observable objects, one for complex logic that requires properties and methods (as a ViewModel) and sharing data across the whole app. The topics described are:

0:52 - Why @State properties aren't enough?
4:47 - Observable Objects
7:37 - Can I use observable objects with @State property wrapper?
10:56 - @StateObject & @ObservedObject
13:31 - ObservableObject example: ViewModel
17:48 - Usage of @Published properties in Observable objects
20:30 - ObservableObject example: User Model across whole app
26:40: - TL;DW: Summary
