Which property wrapper to use depends on your data

• Your data is prone to change

  • Your data will be likely to shared by a lot of subviews

    Use (observable class, @Published) → @StateObject → EnvironmentObject → @EnvironmentObject chain

  • Your data will be likely to only shared by a few subviews

    Use (observable class, @Published) → @StateObject → @ObservedObject chain

• Your data is more likely to keep the same (Value Types such as Bool, Int, Enum, Struct)

  • Shared by a lot of subviews

    Use struct → @State → EnvironmentObject → @EnvironmentObject chain

  • Shared by limited subviews

    Use struct → @State → @Binding chain
