UITableViewCell not clickable when Blinking animation is implemented on it

Question

No action is performed on UITableViewCell when blinking animation is implemented, it starts blinking that is fine but not clickable or swipable. I have tried some solutions but unable to fix it. Code is below.

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        
            cell.backgroundColor = UIColor.colorWithHexString(hexStr: "#FDFAEB")
            cell.blink()

        return cell
    }

Animation extension code:

extension UIView {
    func blink() {
        self.alpha = 0.5;
        UIView.animate(withDuration: 0.7, //Time duration you want,
                       delay: 0.0,
                       options: [.curveEaseInOut, .autoreverse, .repeat],
                       animations: { [weak self] in self?.alpha = 1.0 },
                       completion: { [weak self] _ in self?.alpha = 0.8 })
    }
}

Please tell me, what is the reason, and how can I fix this?

By default user interaction is disabled during animations. you need to add the .allowUserInteraction option to your set of options.

(And note that if you're animating a view's position the user won't be able to tap on the view as it moves. Behind the scenes, a view jumps to it's destination position as soon as the animation begins. It only appears to move across the screen. If you want to handle tapping on a view as it moves across the screen it's a lot more complicated.)
