UIViewRepresentable UITextField在连接到ObservableObject的@Published属性时跳过第一个字符

import SwiftUI
import Combine

class MyData: ObservableObject {
    @Published var text: String = ""
}

struct ContentView: View {
    @ObservedObject var myData = MyData()

    var body: some View {
        TextFieldWrapper(text: $myData.text)
    }
}

struct TextFieldWrapper: UIViewRepresentable {
    @Binding var text: String

    func makeCoordinator() -> Coordinator {
        Coordinator(self)
    }

    func makeUIView(context: Context) -> UITextField {
        let textField = UITextField()
        textField.delegate = context.coordinator
        return textField
    }

    func updateUIView(_ uiView: UITextField, context: Context) {
        uiView.text = text
    }

    class Coordinator: NSObject, UITextFieldDelegate {
        var parent: TextFieldWrapper

        init(_ textFieldWrapper: TextFieldWrapper) {
            parent = textFieldWrapper
        }

        func textField(_ textField: UITextField, shouldChangeCharactersIn range: NSRange, replacementString string: String) -> Bool {
            // Skip the first character
            if range.location == 0 && range.length == 0 {
                return false
            }
            return true
        }

        func textFieldDidChangeSelection(_ textField: UITextField) {
            DispatchQueue.main.async {
                self.parent.text = textField.text ?? ""
            }
        }
    }
}
