Detect if user tapped the screen, including Buttons, in SwiftUI

Question

I've been trying to use .onTapGesture to detect if the user taps on the screen. However, I noticed that it doesn't get triggered if the user taps on actionable elements like buttons and pickers. Is there a way to detect if the user taps on the screen, including these actionable elements without having to manually call my viewTapped function for each button, picker, etc. separately?

Here's the code I used to test this.

struct ContentView: View {
    @State var mode = 0
        
    var body: some View {
        ZStack {
            VStack {
                Text("Hello, world!")
                    .padding()
                
                Picker(
                    selection: $mode,
                    label: Text("Picker")) {
                    Text("Option 1").tag(0)
                    Text("Option 2").tag(1)
                }
                .pickerStyle(SegmentedPickerStyle())
                .frame(width: 200)
                .foregroundColor(.white)
                .padding()
                
                Button {
                    print("button clicked")
                } label: {
                    Text("Click me")
                }
                .padding()
            }
        }
        .frame(maxWidth: .infinity, maxHeight: .infinity)
        .background(Color.green)
        .onTapGesture {
            viewTapped()
        }
    }
    
    public func viewTapped() {
        print("view tapped")
    }
}

So you want both button clicked and view tapped printed? — aheze

If you need to detect touches simultaneity, you need the simultaneousGesture modifier instead. like:


.simultaneousGesture(
    TapGesture()
        .onEnded {
            viewTapped()
        }
)
