• NSHostingController: a view controller that wraps and manages a SwiftUI view hierarchy for integration into UIKit/AppKit-based applications.

• Property Wrapper: adds a layer of separation between code that manages how a property is stored and the code that defines a property.

• Marco refers to compile-time code transformations that generate repetitive or boilerplate code automatically.

• A State property always instantiates its default value when SwiftUI instantiates the view.
