navigate with NavigationStack

Question

I am new to SwiftUI framework. I am trying to implement NavigationStack. I want to navigate on button action instead of using NavigationLink. The reason behind that is, I need to navigate once a particular function get performed on button action.

struct AView: View {
    @State private var actionss = [Int]()

    var body: some View {
        NavigationStack(path: $actionss) {
            VStack {
                Button("test") {
                    actionss.append(0)
                }
            }
            .navigationDestination(for: Int.self) { _ in
                BView()
            }
        }
    }
}

Above code of AView is working fine to navigate BView. The only thing is I am not able to navigate on CView from BView without using NavigationLink.

I need to perform particular function before navigate from BView to CView as well.

Does this answer your question? Make Custom SwiftUI Views with ObservedObjects compatible with NavigationLink iOS 16 — user10119132

Assuming that the work is done on BView you can use .navigationDestination as well:

struct AView: View {
    @State private var actionss  = [Int]()

    var body: some View {

        NavigationStack(path:$actionss) {
            VStack{
                Button("show BView") {
                    actionss.append(0)
                }
            }
            .navigationDestination(for: Int.self) { data in
                BView()
            }
            .navigationTitle("AView")
        }
    }
}

struct BView: View {

    @State var show: Bool = false

    var body: some View {

        VStack {
            Button("show CView") {
                show = true
            }
        }
        .navigationDestination(isPresented: $show) {
            CView()
        }
        .navigationTitle("BView")
    }
}

struct CView: View {

    var body: some View {
        Text("Hello")
            .navigationTitle("CView")
    }
}

im using a button and the navigation destination, but im getting the view Below the NavigationBar with another navigationBar... in presented view there's no navigationStack so there shouldn't be another navigation bar below the parent one, Can anyone point me in where to look for the bug ?
