SwiftUI TapGesture 无法与 iOS 列表中的 NavigationLink 一起使用

Question

When I use .simultaneousGesture(TapGesture().onEnded{ //code to run }) on a NavigationLink in SwiftUI for iOS, the code runs fine and the link opens.

However, if the NavigationLink is in a List , the code runs but the link does not open.

Is there another way I can run some code after the List NavigationLink is tapped, but before the TextEditor appears?

Using .onAppear on the TextEditor , is not suitable because I need the code to run before the TextEditor appears - partly due to a bug with TextEditor 's re-rendering and partly to keep things flowing in the right order.

Code to replicate the issue:

import SwiftUI

struct ContentView: View {
    @State private var textString = ""
    @State private var listMembers = ["Link A", "Link B", "Link C"]
    var body: some View {
        NavigationView {
            VStack {
                List(listMembers, id: \.self) { member in
                    NavigationLink(member, destination: TextEditor(text: $textString))
                        .simultaneousGesture(TapGesture().onEnded {
                            textString = "Link A, B, or C was tapped."
                            print(textString)
                    })
                }
                NavigationLink("Link D", destination: TextEditor(text: $textString))
                    .simultaneousGesture(TapGesture().onEnded {
                        textString = "Link D was tapped."
                    })
            }
        }
    }
}

struct ContentView_Previews: PreviewProvider {
    static var previews: some View {
        ContentView()
    }
}

Thank You!

The best I could come up with is using ForEach instead of List. It requires more formatting to make it look nice, but it seems to solve the problem.

import SwiftUI

struct ContentView: View {
    @State private var textString = ""
    @State private var listMembers = ["Link A", "Link B", "Link C"]
    var body: some View {
        NavigationView {
            VStack {
                /*List(listMembers, id: \.self) { member in
                    NavigationLink(member, destination: TextEditor(text: $textString))
                        .simultaneousGesture(TapGesture().onEnded {
                            textString = "Link A, B, or C was tapped."
                            print(textString)
                    })
                }*/
                ForEach(listMembers, id: \.self) { member in
                    NavigationLink(member, destination: TextEditor(text: $textString))
                        .simultaneousGesture(TapGesture().onEnded {
                            textString = "Link A, B, or C was tapped."
                            print(textString)
                    })
                }
                NavigationLink("Link D", destination: TextEditor(text: $textString))
                    .simultaneousGesture(TapGesture().onEnded {
                        textString = "Link D was tapped."
                    })
            }
        }
    }
}

struct ContentView_Previews: PreviewProvider {
    static var previews: some View {
        ContentView()
    }
}
