如何从工具栏中关闭键盘？

Question

这个问题最好用代码来描述。

struct ContentView: View {
    enum FocusedField {
        case type1
        case type2
    }

    @State private var text: String = ""

    @FocusState private var focusedField: FocusedField?

    var body: some View {

        TextField("Type 1", text: $text)
            .focused($focusedField, equals: .type1)
        
        .toolbar {
            ToolbarItem(placement: .keyboard) {
                TextField("Type 2", text: $text)
                    .focused($focusedField, equals: .type2)
                    .onSubmit {
                        focusedField = nil // This will switch to type1 instead of dismissing.
                    }
            }
        }

    }
}

控制台会输出：

-[RTIInputSystemClient remoteTextInputSessionWithID:performInputOperation:]  perform input operation requires a valid sessionID. inputModality = Keyboard, inputOperation = <null selector>, customInfoType = UIEmojiSearchOperations

public func HideKeyboard() {
    #if canImport(UIKit)
    UIApplication.shared.sendAction(#selector(UIResponder.resignFirstResponder), to: nil, from: nil, for: nil)
    #endif
}
