Assign row value of uipickerView to dynamically created uitextfields - ios

Question

I have a booking app, where user can book a serviceName and servantName, i have to create dynamic (incremental) UITextFields for those two types, those TextFields get filled from Two UIPickerViews (PickerViews works fine).
How can i assign text to TextFields, which is dynamically created from those pickerViews.
I created TextFieldss using Autolayout in scrollView as below function
func addBookingRow(firstTime: Bool) {
let containerView = UIView()
containerView.backgroundColor = .white
containerView.layer.cornerRadius = 5
containerView.layer.borderColor = .white
containerView.layer.borderWidth = 2
containerView.tag = count
contentView.addSubview(containerView)
containerView.translatesAutoresizingMaskIntoConstraints = false
if firstTime {
containerView.topAnchor.constraint(equalTo: contentView.topAnchor, constant: 10).isActive = true
} else {
containerView.topAnchor.constraint(equalTo: bookedServices[count - 1].bottomAnchor, constant: 10).isActive = true
}
containerView.leadingAnchor.constraint(equalTo: contentView.leadingAnchor, constant: 16).isActive = true
containerView.trailingAnchor.constraint(equalTo: contentView.trailingAnchor, constant: -16).isActive = true
let serviceNameTF = CustomTextField()
serviceNameTF.backgroundColor = .white
serviceNameTF.placeholder = "Choose Service"
serviceNameTF.font = UIFont(name: "RB", size: 17)
serviceNameTF.textAlignment = .right
serviceNameTF.tag = count
containerView.addSubview(serviceNameTF)
setupPickerViews(textField: serviceNameTF, picker: serviceNamePicker)
serviceNameTF.addTarget(self, action: #selector(self.serviceNameIsTapped), for: .touchDown)
serviceNameTF.translatesAutoresizingMaskIntoConstraints = false
serviceNameTF.topAnchor.constraint(equalTo: containerView.topAnchor, constant: 5).isActive = true
serviceNameTF.leadingAnchor.constraint(equalTo: containerView.leadingAnchor, constant: 5).isActive = true
serviceNameTF.trailingAnchor.constraint(equalTo: containerView.trailingAnchor, constant: -5).isActive = true
serviceNameTF.heightAnchor.constraint(equalToConstant: 40).isActive = true
let workerTF = CustomTextField()
workerTF.backgroundColor = .white
workerTF.placeholder = "Choose Servant"
workerTF.font = UIFont(name: "RB", size: 17)
workerTF.textAlignment = .right
workerTF.tag = count
containerView.addSubview(workerTF)
setupPickerViews(textField: workerTF, picker: workerPicker)
workerTF.addTarget(self, action: #selector(self.workerTFIsTapped), for: .touchDown)
workerTF.translatesAutoresizingMaskIntoConstraints = false
workerTF.topAnchor.constraint(equalTo: serviceNameTF.bottomAnchor, constant: 5).isActive = true
workerTF.leadingAnchor.constraint(equalTo: containerView.leadingAnchor, constant: 5).isActive = true
workerTF.trailingAnchor.constraint(equalTo: containerView.trailingAnchor, constant: -5).isActive = true
workerTF.heightAnchor.constraint(equalToConstant: 40).isActive = true
let price = UILabel()
price.font = UIFont(name: "RB", size: 17)
price.textColor = .white
containerView.addSubview(price)
price.translatesAutoresizingMaskIntoConstraints = false
price.topAnchor.constraint(equalTo: workerTF.bottomAnchor, constant: 5).isActive = true
price.leadingAnchor.constraint(equalTo: containerView.leadingAnchor, constant: 5).isActive = true
price.trailingAnchor.constraint(equalTo: containerView.trailingAnchor, constant: -5).isActive = true
price.heightAnchor.constraint(equalToConstant: 40).isActive = true
containerView.bottomAnchor.constraint(equalTo: price.bottomAnchor, constant: 5).isActive = true
contentView.bottomAnchor.constraint(greaterThanOrEqualTo: containerView.bottomAnchor, constant: 250).isActive = true
bookedServices.append(containerView)
count += 1
}
