You can add targets for the specific events

class MyTextField: UITextField {
    override init(frame: CGRect) {
        super.init(frame:frame)
        commonInit()
    }
    required init?(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)
        commonInit()
    }
    func commonInit() {
        self.addTarget(self, action: #selector(didBegin), for: .editingDidBegin)
        self.addTarget(self, action: #selector(didEnd), for: .editingDidEnd)
    }
    @objc func didBegin() {

    }
    @objc func didEnd() {

    }
}
