问题 I'm trying to figure out the best way to build a simple settings screen bound to UserDefaults . Basically, I have a Toggle and I want: the value a UserDefault to be saved any time this Toggle is changed (the UserDefault should be the source of truth) the Toggle to always show the value of the UserDefault I have watched many of the SwiftUI WWDC sessions, but I'm still not sure exactly how I should set everything up with the different tools that are available within Combine and SwiftUI.

问题 I'm currently getting familiar with SwiftUI and Combine frameworks. And I'm not really getting the difference between these two approaches. When we have to keep track of some data (say, a list of tasks), we can declare a @State variable, and it's change will automatically send notification and update current view. However, it looks like it can also be done this way: class TaskList: ObservableObject{ //a list that's going to be modified and updated on different occasions @Published var list:
