SwiftUI, How to Use Programmatic Navigation Using Value, with different NavigationDestinations - swiftui

Question

I am struggling to get my head around how to use programmatic navigation with multiple destination views which take the same type of value. In the following code I can successfully navigate from ContentView to View2, but would like to navigate from View2 to View3 by adding a value to the path.
The navigationDestination in ContentView has View2 specified. How/where do I add a second navigationDestination to View3? If I add a navigationDestination in View2 pointing to View3 then it doesn't work, as it uses the View1's navigationDestination as it is closer to root. I would appreciate some guidance on how to approach this problem. Many thanks in advance.
struct ContentView: View {
#State private var path = NavigationPath()
var body: some View {
NavigationStack(path: $path) {
NavigationLink(value: "view2") {
Text("Go to View2")
}
.navigationDestination(for: String.self) { destination in
View2(someParameterA: destination)
}
.navigationTitle("ContentView")
}
}
}
struct View2: View {
#State var someParameterA: String
var body: some View {
VStack {
Text(someParameterA)
NavigationLink(value: "view3") {
Text("Go to View3")
}
}
.navigationTitle("View 2")
}
}
struct View3: View {
#State var someParameterB: String
var body: some View {
Text(someParameterB)
.navigationTitle("View 3")
}
}
I've managed to hack the following solution together which works but is there a better approach?
enum DestinationView {
case view2
case view3
}
struct NavStruct: Equatable, Hashable {
var destinationView: DestinationView
var param: String
}
class ViewSelector {
#ViewBuilder
static func viewForDestination(_ destination: DestinationView, _ param: String) -> some View {
switch destination {
case .view2:
View2(someParameterA: param)
case .view3:
View3(someParameterB: param)
}
}
}
struct ContentView: View {
#State private var path = NavigationPath()
var body: some View {
NavigationStack(path: $path) {
NavigationLink(value: NavStruct(destinationView: .view2, param: "view2")) {
Text("Go to View2")
}
.navigationDestination(for: NavStruct.self) { destination in
ViewSelector.viewForDestination(destination.destinationView, destination.param)
}
.navigationTitle("ContentView")
}
}
}
struct View2: View {
#State var someParameterA: String
var body: some View {
VStack {
Text(someParameterA)
NavigationLink(value: NavStruct(destinationView: .view3, param: "view3")) {
Text("Go to View3")
}
}
.navigationTitle("View 2")
}
}
struct View3: View {
#State var someParameterB: String
var body: some View {
VStack {
Text(someParameterB)
}
.navigationTitle("View 3")
}
}
