ios – Forestall NavigationLink popping again when the record merchandise is faraway from the record

I’ve the follwing SwiftUI view and units is a state repeatedly getting up to date from dad or mum view. If I navigate to DetailView by one of many hyperlink and the corresponding system is faraway from units whereas I’m viewing its DetailView, the navigation pops again. How do I forestall it from popping again even when system is faraway from units?

class Datasource : ObservableObject{
    @Printed public var units : [devices]
}

struct ContentView: View {
    
    @StateObject personal var datasource = Datasource()
    
    var physique: some View {
        NavigationView {
            DeviceList(units: datasource.units)
                .padding()
                .navigationTitle("Demo")
                .navigationBarTitleDisplayMode(.inline)
        }.navigationViewStyle(.stack)
    }
}

struct DeviceList: View{
    var units: [Device]
    var physique: some View{
        if(units.isEmpty)
        {
            Textual content("Scanning...")
        }
        else
        {
            ScrollView{
                LazyVStack {
                    ForEach(units) { system in
                        NavigationLink{
                            DetailView(system: Gadget)
                        } label: {
                            DeviceItem(system: Gadget)
                        }
                        .buttonStyle(.plain)
                    }
                }
            }
        }
        
    }
}

I’ve discovered this publish which talked about an answer to pause the replace of ObservableObject, which appears fixing my drawback however I do not need to modify my datasource to PausableObservableObject. As an alternative I wish to create a generic class class Pausable<T> : PausableObservableObject to encapsulate my datasource, however I do not know the proper strategy to do it. Right here is my try which isn’t efficiently.

class Pausable<T> : PausableObservableObject{
    @Printed var worth: T
    
    personal var sink: AnyCancellable?
    
    init(initialValue:T, writer: Printed<T>.Writer) {
        self.worth = initialValue
        tremendous.init()
        self.$worth = writer
        sink = writer.sink {
            self.worth = $0
            self.publishWillUpdate()
        }
    }
}
