Hi all,

Is there anyone who knows how you could display the contents of an array inside a list and have the row content navigate to a new view when you click on it AND execute an action?

I already found a solution online where they used ".simultaneousGesture(TapGesture())" but besides the fact I don't like the solution, it also does not work when used inside a List.

        List {
            ForEach(gameState.tables, id: \.self) { table in
                NavigationLink(destination: TableView()) {
                    TableRow(table: table.number, difficulty: table.difficulty)
                }
            }
        }

The code I now have is shown above but I also use an "@EnvironmentObject var gameState: GameState" which is shared across all views. Inside this gameState I have a property named "chosenTable". So I'd like to set this property when you click on the row and also navigate to the 'TableView' view. I have to use this property in future views as well which is why I don't want to pass it as an argument.

Any idea if such a thing (performing an action and navigate) is possible at all with SwiftUI?

Hi Nico

I've found a possible solution. I don't know if you like it: How about using the NavigationLink(destination:tag:selection:) variation in combination with a custom binding to track the current selection?

I tested it successfully the code below. I had to use a func to create the binding, so I got around the weird compiler errors. Checkout Pauls quick start article on custom bindings.

BTW: Instead of doing the custom binding below, simply use the NavigationLinks selection: argument directly on your choosenTable variable of your environment object?

struct ContentView: View {

    @ObservedObject var gameState: GameState

    @State var selectedTable: Int?

    var body: some View {
        NavigationView {
            List {
                ForEach(gameState.tables, id: \.self) { table in
                    NavigationLink(destination: TableView(),
                                   tag: table.number,
                                   selection: self.customBinding()) {
                        TableRow(table: table.number, difficulty: table.difficulty)
                    }
                }
            }
        }
    }

    func customBinding() -> Binding<Int?> {
        let binding = Binding<Int?>(get: {
            self.selectedTable
        }, set: {
            print("Table \(String(describing: $0)) chosen")
            self.selectedTable = $0
        })
        return binding
    }
}
