UITextField not triggering action event upon UIDatePicker action event - ios

Question

I have a datePicker that updates my textField. Once the textField data changes is supposed to perform actions(such as verifying data). The problem is that after the datePicker updates the textField, the textField does not perform any actions, regardless of what action event I am using on the textField, such as .ValueChanged.I cannot figure out what the problem is. I noticed though, that if I am to type something in the textField, the action event works.
Here's my code:
class CustomTextField: UITextField, UITextFieldDelegate {
var customDelegate : CustomTextFieldDelegate?
enum type {
case standard
case date
}
var textFieldType : type = .standard {
didSet{
switch self.textFieldType {
case .standard:
break
case .date:
let datePicker = UIDatePicker.MMMddyyyy
self.inputView = datePicker
datePicker.addTarget(self, action: #selector(refreshOnDatePicker(_:)), for: .valueChanged)
self.addTarget(self, action: #selector(checkFieldInput), for: .applicationReserved)
break
}
}
}
#objc private func checkFieldInput(sender: CustomTextField){
guard let fieldInput = self.text else { return }
switch sender.textFieldType {
case .standard:
break
case .date:
customDelegate?.isTextFieldVerified = !fieldInput.isEmpty
break
}
}
#objc private func refreshOnDatePicker(_ selector: UIDatePicker){
self.text = selector.date.formattedMMMMddyyyy
}
}
fileprivate extension UIDatePicker {
class var MMMddyyyy : UIDatePicker {
let currentDate: NSDate = NSDate()
let calendar: NSCalendar = NSCalendar(calendarIdentifier: NSCalendar.Identifier.gregorian)!
calendar.timeZone = NSTimeZone(name: "UTC")! as TimeZone
let components: NSDateComponents = NSDateComponents()
components.calendar = calendar as Calendar
components.year = -100
let minDate: NSDate = calendar.date(byAdding: components as DateComponents, to: currentDate as Date, options: NSCalendar.Options(rawValue: 0))! as NSDate
let dp = UIDatePicker()
dp.datePickerMode = .date
dp.minimumDate = minDate as Date
dp.maximumDate = currentDate as Date
dp.backgroundColor = UIColor.white
return dp
}
}
fileprivate extension Date {
/// date formatted type "MMMM dd, yyyy"
var formattedMMMMddyyyy: String {
let formatter = DateFormatter()
formatter.dateFormat = "MMMM dd, yyyy"
return formatter.string(from: self)
}
}

Try this
#objc private func refreshOnDatePicker(_ selector: UIDatePicker){
self.text = selector.date.formattedMMMMddyyyy
self.checkFieldInput(sender:self)
}
