SwiftUI TextField which is perfectly in sync with the text binding

RigidTextField.swift

import SwiftUI

struct RigidTextField: View {
    @Binding private var externalText: String
    @State private var internalText: String
    private let title: String

    init(_ title: String, text: Binding<String>) {
        self.title = title
        _externalText = text
        internalText = text.wrappedValue
    }

    var body: some View {
        TextField(title, text: $internalText)
            .onChange(of: internalText) {
                guard internalText != externalText else {
                    return
                }
                // This works, don't change it!
                externalText = internalText
                internalText = externalText
            }
            .onChange(of: externalText) {
                guard internalText != externalText else {
                    return
                }
                internalText = externalText
            }
    }
}
