SOLVED: A quick question about the syntax of a @Published variable

In Paul's iDine example we have an Order object

    class Order: ObservableObject {

        @Published var items = [MenuItem]()
        ...

what does the () notify here? Default getters and setters?

var items: [MenuItem]  // This is a declaration of a variable, an array of MenuItems
var items = [MenuItem]()  // This declares a variable and assigns the variable to a new instance of the type
// Basically the () calls an init

Oh yes, thanks @wieniek for clarifying that ... for some reason I couldn't parse it, not used to it. We are creating an empty array of a certain type using initializer syntax; specifically initializing Array<Element> where <Element> is our MenuItem object type. Got it!

Perhaps I was lookimg for var items: [MenuItem] = [] alternative.
