Please help me get rid of this problem:

Steps to reproduce my problem:

1. Tap "Edit My Name" Button

2. Inside .sheet, tap on the TextField and then with keyboard still shown, scroll all the way down

3. Tap on the Button "Delete Name"

4. Here is the problem:

   confirmationDialog appears only for one second, and then disappears, not giving the user any chance (or less than one second chance) to tap one of the confirmationDialog's Buttons!

Here's my code:

ContentView.swift

import SwiftUI

struct ContentView: View {
    @State private var myName = "Joe"
    @State private var isEditingName = false
    
    var body: some View {
        Text("My name is: \(myName)")
        Button("Edit My Name") {
            isEditingName = true
        }
        .padding()
        .sheet(isPresented: $isEditingName) {
            EditView(name: $myName)
        }
        
    }
}

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

EditView.swift

import SwiftUI

struct EditView: View {
    @Binding var name: String
    @State private var isShowingConfirmationDialog = false
    
    var body: some View {
        Form {
            Section {
                TextField("Name", text: $name)
            }
            Section {
                VStack {
                    ForEach(0..<50, id: \.self) { number in
                        Text("\(number)")
                    }
                }
            }
            Section {
                deleteNameWithConfirmationDialog
            }
        }
    }
    
    private var deleteNameWithConfirmationDialog: some View {
        Button("Delete Name", role: .destructive) {
            isShowingConfirmationDialog = true
        }
        .confirmationDialog("Are you sure you want to delete name?", isPresented: $isShowingConfirmationDialog) {
            Button("Delete Name", role: .destructive) {
                name = ""
            }
            Button("Cancel", role: .cancel) { }
        } message: {
            Text("Are you sure you want to delte name?")
        }
    }
    
}

struct EditView_Previews: PreviewProvider {
    static var previews: some View {
        EditView(name: .constant(String("Joe")))
    }
}

CodePudding user response：

It works if you move the .confirmationDialogue out of the Form:

struct EditView: View {
    @Binding var name: String
    @State private var isShowingConfirmationDialog = false
    
    var body: some View {

        Form {
            Section {
                TextField("Name", text: $name)
            }
            Section {
                VStack {
                    ForEach(0..<50, id: \.self) { number in
                        Text("\(number)")
                    }
                }
            }
            Section {
                Button("Delete Name", role: .destructive) {
                    isShowingConfirmationDialog = true
                }
            }
        }
        
        .confirmationDialog("Are you sure you want to delete name?", isPresented: $isShowingConfirmationDialog) {
            Button("Delete Name", role: .destructive) {
                name = ""
            }
            Button("Cancel", role: .cancel) { }
        } message: {
            Text("Are you sure you want to delete name?")
        }
    }
}
