Hello, I'm trying to add an alert on macOS: on this alert, there are TextField() and a Button that triggers a simple print. On iOS, the same View is working, but on macOS, the button is ignored: the alert is closing but the print is not displayed.

Can somebody try this, and confirm this is a bug on SwiftUI on macOS? Thanks!

Do you have a code sample you can share?

I work primarily on macOS, and I haven't had problems with Button, but there are definitely some differences between SwiftUI on macOS and iOS.

Hi, here is a small example. If you uncomment the TextField, nothing is printed.

import SwiftUI

struct ContentView: View {
    @State var showAlert = false
    @State var textFieldValue = ""

    func printSomething() {
        print("If I'm printed, action was working")
    }

    var body: some View {
        NavigationStack {
            Button("Open alert") {
                showAlert.toggle()
            }
        }.alert("My alert", isPresented: $showAlert) {
            // TextField("My text field", text: $textFieldValue)
            Button("OK") {
                printSomething()
            }
        }
        .navigationTitle("Test")
    }
}

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

I did this and it works ok

struct ContentView: View {
    @State var showAlert = false
    @State var textFieldValue = ""

    var body: some View {
        NavigationStack {
            Button("Show Alert") {
                showAlert = true
            }
        }
        .alert("My Alert", isPresented: $showAlert) {
            TextField("Enter Here", text: $textFieldValue)

            Button {
                printSomething()
            } label: {
                Text("OK")
            }

            Button(role: .cancel) {
                // no action needed
            } label: {
                Text("Cancel")
            }

        }
    }

    func printSomething() {
        print("This what was entered in textfield: '\(textFieldValue)'")
    }
}

printed

This what was entered in textfield: 'TextFieldValue'

Okay thank you!

So thanks to your example, I investigated and found that by default, on macOS, the first button have no effect. If I duplicate the button on my example, the seconds is working correctly.
