• Use @State for simple properties that belong to a single view. They should usually be marked private.

• Use @ObservedObject for complex properties that might belong to several views. Most times you’re using a reference type you should be using @ObservedObject for it.

• Use @StateObject once for each observable object you use, in whichever part of your code is responsible for creating it.

• Use @EnvironmentObject for properties that were created elsewhere in the app, such as shared data.

Of the four you will find that @ObservedObject is both the most useful and the most commonly used, so if you’re not sure which to use start there.
