ios – Want Assist Sustaining Swift Atmosphere Object

Making an attempt to put a SwiftUI View right into a ViewController utilizing UIHostingController, however receiving the next error:

No ObservableObject of kind UIStateModel discovered. A View.environmentObject(_:) for UIStateModel could also be lacking as an ancestor of this view.

All assist appreciated, I have been fairly caught :(.

ViewController.swift

class ViewController: UIViewController {
    @EnvironmentObject var UIModel: UIStateModel
    var uiState: UIStateModel = UIStateModel()
    
    
    override func viewDidLoad() {
        tremendous.viewDidLoad()
        addCarousel()
    }
    
    func addCarousel(){
        let snapC : SnapCarousel
        let contentView : UIHostingController<SnapCarousel>
        uiState = UIStateModel()
        snapC = SnapCarousel( UIState: uiState )
        contentView = UIHostingController(rootView: snapC)
        addChild(contentView)
        view.addSubview(contentView.view)
        contentView.didMove(toParent: self)
    }
    
}

Carousel.swift

struct SnapCarousel: View {
    var UIState: UIStateModel
    //Carousel instantiation 
}

struct Card: Decodable, Hashable, Identifiable {
    //code
}

public class UIStateModel: ObservableObject {
    @Revealed var activeCard: Int = 0
    @Revealed var screenDrag: Float = 0.0
}

struct Carousel<Gadgets : View> : View {
    @EnvironmentObject var UIState: UIStateModel
    //card administration
}

struct Canvas<Content material : View> : View {
// view supervisor 
}

struct Merchandise<Content material: View>: View {
    @EnvironmentObject var UIState: UIStateModel
   //code for card view
}
