Get data from view after it gets added on screen using ForEach

added code details below

Below is the code that I have currently

struct CheckListCard: View {
   
  @Binding var checkListData : ChecklistModel
  @State var statusList: [String] = []
  @State var currentStatus : String = ""
  @State var currentRemark: String = ""
  @Binding var enableButtonBool: Bool
   
  var body: some View {
    VStack{
      Text("Description").padding()
        .onAppear(){
          addData()
        }
      if checkListData.description != nil{
        Text(checkListData.description!)
          .padding()
      }
      Text("Status").padding()
      if checkListData.status != nil {
        Picker("Status", selection: $currentStatus ) {
          ForEach(GeneralMethods().uniqueElementsFrom(array: statusList), id: \.self){ status in
            Text(status)
          }
        }.pickerStyle(SegmentedPickerStyle())
        .padding()
        .disabled(!enableButtonBool)
         
      }
      Text("Remarks")
      if checkListData.remarks != nil{
        TextField("Remarks", text: $currentRemark)
          .disabled(!enableButtonBool)
          .padding()
          .background(Color(.white))
          .cornerRadius(8)
          .accentColor(.gray)
           
      }else{
        TextField("Remarks", text: $currentRemark)
          .disabled(!enableButtonBool)
          .padding()
          .background(Color(.white))
          .cornerRadius(8)
           
      }
    }

struct CheckListSheet: View {
   
  @State var taskId: Int
  @State var pmTaskResponse : PmTaskResponse
  @State var checklistResponse: [ChecklistModel] = [ChecklistModel()]
  @State var enableButtonBool: Bool = false
  var body: some View {
     
    Text("Checklist Items")
      .padding()
      .font(.title)
     
    ScrollView{
       
      ForEach(checklistResponse, id:\.self){ checklist in
        CheckListCard(checkListData: Binding(get: {
          return checklist
        }, set: { (newValue) in
          checklistResponse.append(newValue)
        }) , enableButtonBool: $enableButtonBool)
      }
      if enableButtonBool{
        Button("Update"){
          updateCheckList()
        }.buttonStyle(MainButton())
      }
    }
    .onAppear(){
      getChecklists()
    }
     
  }
   

@OOPer I have attached the file for you to see. Let me know if you need anything else.

I have refactored the file and I am sending it again.

Thanks for showing the refactored code. It compiled fine. I needed to add enableButtonBool = true, but it was a great help to guess what you want to do. (I still do not understand some parts of the code, but it may be better to show what I guessed.)

I may be mistaking something, but you may want to do something like this:

import SwiftUI

struct ChecklistModel: Codable, Hashable {
    var description, remarks, status: String?
}

struct CheckListCard: View {
    @Binding var checkListData : ChecklistModel
    @State var statusList: [String] = []
    @Binding var enableButtonBool: Bool
    
    var body: some View {
        let currentStatus = Binding<String>(
            get: {checkListData.status ?? ""},
            set: {checkListData.status = $0})
        let currentRemark = Binding<String>(
            get: {checkListData.remarks ?? ""},
            set: {checkListData.remarks = $0})
        VStack{
            Text("Description").padding()
                .onAppear(){
                    addData()
                }
            if let description = checkListData.description {
                Text(description)
                    .padding()
            }
            Text("Status").padding()
            if checkListData.status != nil {
                Picker("Status", selection: currentStatus) {
                    ForEach(statusList, id: \.self){ status in
                        Text(status)
                    }
                }.pickerStyle(SegmentedPickerStyle())

                .disabled(!enableButtonBool)
