How to control the focus state.

We can listen and control the focus state on a particular input using focused(_:) modifier.

This modifier needs a special type called FocusState to bind the focus state.

Here is an example where we hide the keyboard when the "Sign In" button is tapped.

struct ContentView: View {
    @State private var username = ""
    // 1
    @FocusState private var isFocused: Bool

    var body: some View {
        VStack {
            // 2
            TextField("Username", text: $username)
                .focused($isFocused)
            Button("Sign In") {
                // 3
                isFocused = false
            }
        }
        .padding()
    }
}

1 We create a @FocusState variable to bind with the focus state of the text field.
2 We bind the focus state using .focused($isFocused) modifier.
3 To dismiss the keyboard, we unfocus the text field by setting the focus state to false, isFocused = false.

When we tapped the text field:

1. It will gain focus.
2. isFocused will become true.
3. And the keyboard will show.

When we set isFocused back to false:

1. The text field gives up its focus.
2. And the keyboard will dismiss.
