Button title change in Swift

An example on how to toggle the title of the button when tapping:

The buttonState could also be changed anywhere in code.

struct ContentView: View {
    @State var buttonTapped = false
    
    var body: some View {
        Button(action: {
            buttonTapped.toggle()
            
        }) {
            if buttonTapped {
                Text("Second")
            } else {
                Text("First")
            }
        }

        Text("Hello, world!")
            .onTapGesture {  // Can toggle title here as well
                buttonTapped.toggle()
            }
    }
}
