update Solution For Swift 5

In This solution, You will go to next Field. And When You Press Erase will come at previous text field.

Step 1: Set Selector for Text Field

override func viewDidLoad() {
        super.viewDidLoad()

         otpTextField1.addTarget(self, action: #selector(self.textFieldDidChange(textField:)), for: UIControl.Event.editingChanged)
    otpTextField2.addTarget(self, action: #selector(self.textFieldDidChange(textField:)), for: UIControl.Event.editingChanged)
    otpTextField3.addTarget(self, action: #selector(self.textFieldDidChange(textField:)), for: UIControl.Event.editingChanged)
    otpTextField4.addTarget(self, action: #selector(self.textFieldDidChange(textField:)), for: UIControl.Event.editingChanged)
        
    }

Step 2: Now We will handle move next text Field and Erase text Field.

@objc func textFieldDidChange(textField: UITextField){
        let text = textField.text
        if  text?.count == 1 {
            switch textField{
            case otpTextField1:
                otpTextField2.becomeFirstResponder()
            case otpTextField2:
                otpTextField3.becomeFirstResponder()
            case otpTextField3:
                otpTextField4.becomeFirstResponder()
            case otpTextField4:
                otpTextField4.resignFirstResponder()
            default:
                break
            }
        }
        if  text?.count == 0 {
            switch textField{
            case otpTextField1:
                otpTextField1.becomeFirstResponder()
            case otpTextField2:
                otpTextField1.becomeFirstResponder()
            case otpTextField3:
                otpTextField2.becomeFirstResponder()
            case otpTextField4:
                otpTextField3.becomeFirstResponder()
            default:
                break
            }
        }
        else{

        }
    }

Important Note: Don't Forget To set Delegate.
