@FocusState 在运行 iOS 16 的 Xcode14 上根本不起作用

Question

I am unable to make this work as intended, I wrote this simple code in Xcode 14 beta, I'm trying to focus the TextField using a Button. No results...

XCODE Version 14.0 beta 5 (14A5294e)

@FocusState private var isTexting: Bool
@State private var text: String = ""

var body: some View {
    VStack(spacing: 0) {
        TextField("00000000", text: $text)
            .focused($isTexting)
        Button {
            isTexting = true
        } label: {
            Text("start texting")
        }

    }
    .frame(maxWidth: .infinity, maxHeight: .infinity)
}
