Update not working?

[hfossli]

struct ContentView: View {
    @State var counter = 0
    
    var body: some View {
        VStack {
            
            Text("Hello no \(counter) from SwiftUI")
                .padding()
            
            UILabel() // <- This can be any `UIKit` view.
                .swiftUIView(layout: .intrinsic) // <- This is returning a SwiftUI `View`.
                .set(\.text, to: "Hello no \(self.counter) from UIKit") // <- Use key paths for updates.
                .fixedSize()
        }
        .onAppear {
            if counter == 0 {
                schedule()
            }
        }
    }
    
    func schedule() {
        counter += 1
        DispatchQueue.main.asyncAfter(deadline: .now() + 0.5) {
            self.schedule()
        }
    }
}

I expected the UILabel to be updated and behave like my SwiftUI Text-view, but instead it is showing just 0. Also, recreating the UILabel every time the view hierarchy is declared is not a good idea as it may happen many many times. I think this is a fundamental issue with the approach in this library. I find this approach better and easier

import SwiftUI
import UIKit

struct UIViewMaker<ViewType: UIView>: UIViewRepresentable {
    
    typealias UIViewType = ViewType
    
    var make: () -> ViewType = ViewType.init
    var update: (ViewType) -> ()
    
    func makeUIView(context: Context) -> ViewType {
        return make()
    }
    
    func updateUIView(_ uiView: ViewType, context: Context) {
        update(uiView)
    }
}

struct ContentView: View {
    @State var counter = 0
    
    var body: some View {
        VStack {
            
            Text("Hello no \(counter) from SwiftUI")
                .padding()
            
            
            UIViewMaker<UILabel> {
                $0.text = "Hello no \(self.counter) from UIKit"
            }
            .fixedSize()
            
        }
        .onAppear {
            if counter == 0 {
                schedule()
            }
        }
    }
    
    func schedule() {
        counter += 1
        DispatchQueue.main.asyncAfter(deadline: .now() + 0.5) {
            self.schedule()
        }
    }

}

Great find! I think I didn't encounter this earlier because I'm mainly using it for previews myself that come with static data.
