SwiftUI: How to observe a TextField value

TextField : A control that displays an editable text interface.

Multiple ways to observe the SwiftUI TextField value

1. Using Closure
2. Using onChange modifier
3. Using Publisher(Combine)

import SwiftUI
import Combine
struct ContentView: View {
  @State private var Text1 = "" 
  @State private var Text2 = ""
  @ObservedObject var viewModel = ObserveTextFieldValue()
  var body: some View {
     //MARK: Using Closure
       TextField("Enter text1", text: $Text1){ editing in
           print(editing)
       }onCommit: {
           print("Committed")
       }
     //MARK: Using .onChange Modifier
       TextField("Enter text2", text: $Text2).onChange(of: Text2){
           text in
             print(text)
       }
     //MARK: Using Viewmodel and Publisher(Combine)
       TextField("Enter text3", text: $viewModel.value)
    }
}

class ObserveTextFieldValue: ObservableObject {
      @Published var value: String = ""
      private var cancellables = Set<AnyCancellable>()
      init() {
         $value.sink(receiveValue: {val in
               print(val)
        }).store(in: &cancellables)
      }
}
