    func showSettings(selecteIndex : Int) {
        //show menu

        if let window = UIApplication.shared.keyWindow {

            blackView.backgroundColor = UIColor(white: 0, alpha: 0.5)

            blackView.addGestureRecognizer(UITapGestureRecognizer(target: self, action: #selector(handleDismiss)))

            window.addSubview(blackView)

            window.addSubview(bottomView)

            bottomView.addSubview(titlebottomView)

            titlebottomView.addSubview(bottomViewActionLabel)
            titlebottomView.addSubview(doneButton)

            let height: CGFloat = 150
            let y = window.frame.height - height

            bottomView.frame = CGRect(x: 0, y: window.frame.height, width: window.frame.width, height: height)

            titlebottomView.frame = CGRect(x: 0, y: 0, width: window.frame.width, height: 40)

                bottomView.addSubview(pikerViewForGender)

                bottomViewActionLabel.text = "Select your Gender"

                bottomView.addSubview(pikerViewForGender)
                pikerViewForGender.frame = CGRect(x: 0, y: 44, width: bottomView.frame.width, height: bottomView.frame.height - 40)

            self.bottomViewActionLabel.frame = CGRect(x: 13, y: 0, width: 150, height: 40)
            self.doneButton.frame = CGRect(x: window.frame.width - 80 , y: 0, width: 80, height: 40)

            blackView.frame = window.frame
            blackView.alpha = 0

            UIView.animate(withDuration: 0.5, delay: 0, usingSpringWithDamping: 1, initialSpringVelocity: 1, options: .curveEaseOut, animations: {

                self.blackView.alpha = 1

                self.bottomView.frame = CGRect(x: 0, y: y, width: window.frame.width, height: height)


            }, completion: nil)
        }
    }

    func handleDismiss() {


        UIView.animate(withDuration: 0.5, delay: 0, usingSpringWithDamping: 1, initialSpringVelocity: 1, options: .curveEaseOut, animations: {

            self.blackView.alpha = 0

            if let window = UIApplication.shared.keyWindow {
                self.bottomView.frame = CGRect(x: 0, y: window.frame.height, width: window.frame.width, height: window.frame.height)


            }

        }) { (completed: Bool) in

            print("good way ....")

        }
    }

}

alert view code :

extension UIViewController {

   func showAlert(message: String ){

        let alert = UIAlertController(title: "Whoops", message: message, preferredStyle: UIAlertControllerStyle.alert)
        alert.addAction(UIAlertAction(title: "OK", style: UIAlertActionStyle.default, handler: {(_ action: UIAlertAction) -> Void in

            alert.dismiss(animated: true, completion: nil)

        }))
        self.present(alert, animated: true, completion: nil)
    }
}

Answer 1

Your done button is added as subview onto titlebottomView. When you see your done button up there, it means that your titlebottomView is still on your screen, not getting dismissed or brought back. So in your handleDismiss() function, use your desired way to make sure titlebottomView is in some off screen location or bring it back as best practice.
