text field become Empty when table View Scrolled Swift

there is a table View Inside VC2 to Modify or add Contact into phone . the problem it is text fields become blank in Sections when table view scrolled . i found a way to fix this Problem But i cant handle it Properly .

Model : 

class ContactModel : NSObject {
    var identifier : String!
    var thumbnailImageData : UIImage?
    var givenName : String!
    var familyName : String!
    var phoneNumbers : [String]!
    var emailAddresses : [String]!

    override init() {
        self.phoneNumbers = []
        self.emailAddresses = []
        super.init()
    }

VC2 : 

        var contactModel = ContactModel()

        @IBOutlet weak var tvInsert: UITableView!

           override func viewDidLoad() {
                super.viewDidLoad()
        }

            func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

                if indexPath.section == 0 {
                    let cell0 = tableView.dequeueReusableCell(withIdentifier: "InsertTableCell0") as! InsertTableCell0
                    cell0.txtFirstName.text = self.contactModel.givenName
                    cell0.txtLastName.text = self.contactModel.familyName
                    return cell0
                }else if indexPath.section == 1 {
                    let cell1 = tableView.dequeueReusableCell(withIdentifier: "InsertTableCell1") as! InsertTableCell1
                    cell1.btnDelete.addTarget(self, action: #selector(deleteRowDate(_:)), for: .touchUpInside)
                    cell1.txtPhoneNumber.placeholder = "Phone Number"
                    cell1.txtPhoneNumber.text = contactModel.phoneNumbers[indexPath.row]
// here i get textField tag 
                    cell1.txtPhoneNumber.tag = indexPath.row
                    cell1.txtPhoneNumber.delegate = self
                    return cell1
                }else {
                    let cell2 = tableView.dequeueReusableCell(withIdentifier: "InsertTableCell2") as! InsertTableCell2
                    cell2.btnEmail.addTarget(self, action: #selector(deleteRowDate(_:)), for: .touchUpInside)
                    cell2.txtEmail.placeholder = "Email"
                    cell2.txtEmail.text = contactModel.emailAddresses[indexPath.row]
                    return cell2

                }
            }

       func textFieldDidEndEditing(_ textField: UITextField) {

            let index = IndexPath(row: textField.tag, section: 1)
            let cell = tvInsert.cellForRow(at: index) as? InsertTableCell1
            let pointInTable = cell?.txtPhoneNumber.convert(textField.bounds.origin, to: self.tvInsert)
            let textFieldIndexPath = self.tvInsert.indexPathForRow(at: pointInTable!)
            print(textFieldIndexPath)
    }

Create model of your all field you need and set array as blank as follow.

var dict:[String:Any] = [:]
    dict["description"] = ""
    arrGetEducationList.append(EducationDetailsArrModel(JSON: dict)!)
    self.tblEducation.reloadData()

After in you tableview cell set model data like that

    let edu = self.arrGetEducationList[indexPath.row]
    cell.txtSchool.text = edu.edu_institute_name

After that create delegate methods for textfield 

func textFieldDidEndEditing(_ textField: UITextField) {
    let pointInTable = textField.convert(textField.bounds.origin, to: self.tblEducation)
    let IndexPath = self.tblEducation.indexPathForRow(at: pointInTable)
    if let cell = tblEducation.cellForRow(at: IndexPath!) as? AddEducationCell1 {

        if cell.txtSchool == textField{
            arrGetEducationList[(IndexPath?.row)!].edu_institute_name = textField.text!
        }
    }
}

The UITextFields will be get empty for sure, hence you did not update your contactModel with the data typed into that UITextField. Your method textFieldDidEndEditing looks Error prone, however in the end you need to update all needed properties of contactModel within that method.

e.g.:

contactModel.givenName = textField.text

you must have to set textfield's value in your model also. in textFieldDidEndEditing this method.

Your text fields are obviously reused. So, use temporary storage in order to save the temporary content. e.g, you can use 

yourTextField.addTarget(self, action: #selector(textFieldDidChanged(textField:)), for: .editingChanged)

and to catch:

@objc func textFieldDidChange(textField: UITextField){

 storage[textField.tag] = textField.text
}
let storage = [Int: String]()


 func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let tag = tagFromIndexPath(indexPath)
textField.text = storage[tag]
}
