MVVM SwiftUI Tutorial - State Management and Data Flow through SwiftUI - Example Refactoring

In this video we talk about MVVM (Model - View Model - Model), which is a design pattern recommend for SwiftUI 🤩. Next we will see what MVVM means and how it works with SwiftUI. A important part is to understand the data flow. We will see why we use ObservableObject and @Published. We will be talking about the declarative programming in SwiftUI, where “the truth“ comes in. In the view part we will see the difference between @ObservedObject, @StateObject and @EnvironmentObject. We will use it to improve a sample project and take advantage of it when working in the preview and writing unit tests.
