Use this extension for detect specific tableview scrolling in iOS Swift

extension ViewController: UIScrollViewDelegate {
    func scrollViewDidScroll(_ scrollView: UIScrollView) {
        if scrollView == tableName {
            // write logic for tableview disble scrolling
        }
    }
}

As @jarvis12 mentioned in comment, UITableView inherits from UIScrollView and you can take advantage of its delegate methods.

  1. Add a global bool variable which will act as a flag to check current state of scrolling. 

    var isScrolling = false

  2. Add two UIScrollView delegate methods and update isScrolling variable as below:

    func scrollViewWillBeginDragging(_ scrollView: UIScrollView) {
    self.isScrolling = true
}

func scrollViewWillEndDragging(_ scrollView: UIScrollView, withVelocity velocity: CGPoint, targetContentOffset: UnsafeMutablePointer<CGPoint>) {
    self.isScrolling = false
}

  3. In your UITableViewCell simply add following if condition:

    if isScrolling {
    //disable pan gesture
}
else {
    //enable pan gesture
}
