SOLVED: Question about DataController in Ultimate Portfolio App; why class instead of struct?

I just had a quick question about this.. what are the advantages of defining the datacontroller as a class rather than struct (persistence controller) like in the Xcode template core data apps?

So it can be passed around as an EnvironmentObject. Those have to conform to ObservableObject and only classes can do that.
