uitextfield - Set date and time is not displayed in textField / Swift

I created a UITextField and a datePicker as InputView. Everything works except the displaying of the set date and time.

This is my Code:

func setDatePickerAsInputView(target: Any, selector: Selector) {
        
        let screenWidht = UIScreen.main.bounds.width
        let datePicker = UIDatePicker(frame: CGRect(x: 0.0, y: 0.0, width: screenWidht, height: 300))
        datePicker.datePickerMode = .dateAndTime
        self.inputView = datePicker
        
        let toolBar = UIToolbar(frame: CGRect(x: 0.0, y: 0.0, width: screenWidht, height: 30.0))
        self.inputAccessoryView = toolBar
        
        
    }

func setUpDateTextField() {
        
        //DateTextField
        dateTextField.layer.cornerRadius = 25
        dateTextField.layer.borderWidth = 2
        dateTextField.textAlignment = .center
        self.dateTextField.setDatePickerAsInputView(target: self, selector: #selector(dateSelected))
        
        dateTextField.translatesAutoresizingMaskIntoConstraints = false
        dateTextField.widthAnchor.constraint(equalToConstant: 200).isActive = true
        dateTextField.heightAnchor.constraint(equalToConstant: 80).isActive = true
        
        
        let formatter = DateFormatter()
        formatter.dateStyle = .medium
        formatter.timeStyle = .short
        
        dateTextField.text = formatter.string(from: datePicker.date)
    }
    
    @objc func dateSelected() {
        if let datePicker = self.dateTextField.inputView as? UIDatePicker {
            let dateFormatter = DateFormatter()
            dateFormatter.dateStyle = .medium
            dateFormatter.timeStyle = .short
            self.dateTextField.text = dateFormatter.string(from: datePicker.date)
            dateTextField.text = "(datePicker.date)"
        }
        
        self.dateTextField.resignFirstResponder()
        
    }
    

But if I close the datePicker it's still the current (old) date in the TextField and not the date and time I set. Can some help me? Thanks in advance!

You have missed assign target to UIDatePicker````. As you are passing target and selector but not assing to UIDatePicker```

Add this line inside the setDatePickerAsInputView function

datePicker.addTarget(target, action: selector, for: .valueChanged)

Now, dateSelected method call everytime whenever value is changed. So, you need to remove this line self.dateTextField.resignFirstResponder() from function. Or you can change action from .valueChanged to .editingDidEnd
