SwiftUI ForEach refresh makes view pop

I have something like this:


import SwiftUI

struct Overview: View {

    @ObservedObject var firstArray = FirstArray()

    var body: some View {
        Group{
            ScrollView(){
                ForEach(self.firstArray.array, id: \.self){ array in
                    SubView(array: array)
                }
                Spacer()
            }
        }.navigationBarTitle("Overview")
    }
}


struct SubView: View {

    @State var array

    var body: some View {
           NavigationLink(destination: DetailInfo(array: array){
                Image(systemName: "pencil.circle").resizable().frame(width: 30, height: 30)
            }
    }.navigationBarTitle("SubView")
}


struct DetailInfo: View {

    @State var array

    var body: some View {
        List(){
            ForEach(0..<self. array.count, id: \.self){item in
                Text(item)
            }.onDelete(perform: deleteItem)
        }
    }

    func deleteItem(at offsets: IndexSet) {
       self.array.remove(atOffsets: offsets)
    }

}

When I delete an item in the DetailInfo it pops me back to the Overview. Why is that? Is that because of the ForEach "refreshing" in the Overview. How can I stay on the DetailInfo ? When leaving out the id: \.self in Overview it doesn't show this behaviour.

yes, it is because everything gets refresh and so the detail view and the navigationlink won't exist anymore and so the app "jumps" back to the root view

the "normal" solution is: do not delete the item in the detail view but in the list - then there is no problem and you got a nice animation for free from SwiftUI too
