how to make the code simpler and more reusable for navigation links with multi dimension dictionary in swiftui?

Question

I have a multi-level dictionary that I need use to build navigation links. Now I have a 2-level depth dictionary:

let multiDimDict: [String: [[String: [String]]]         


        

Answer 1

I would start by abandoning the use of a dictionary and use a simple recursive struct that provides a more useful model:

struct Item: Identifiable {
    let id = UUID()
    var title: String
    var children: [Item] = []
}

Then you can define a recursive View to display this model:

struct NavView: View { 
    var item: Item

    var body: some View {
        NavigationView {
            List {
                ForEach(item.children) { child in
                    if child.children.isEmpty {
                        Text(child.title)
                    } else {  
                        NavigationLink(destination: NavView(item:child)) {
                            Text(child.title)
                        }
                    }
                }
            }.navigationBarTitle(item.title)
        }
    }
}

Then you can create your hierarchy as required and pass the root to your view:

let root = Item(title:"",children:
    [Item(title:"A",children:
        [Item(title:"A1", children:
            [Item(title:"A11"),Item(title:"A12")]
            )]),
          Item(title:"B",children:
            [Item(title:"B1"),Item(title:"B2")]
        )]
)

NavView(item:root))
