Swipe vertical gesture not working with UITableView

Question

I have UIViewController and I have added a UITableView to it in the storyboard, later I added a swipe Up gesture recognizer to the view, but nothing happened.

this is my code

import UIKit

class ViewController: UIViewController, UITableViewDelegate, UITableViewDataSource, UIGestureRecognizerDelegate {

@IBOutlet weak var tableview: UITableView!

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.

    let swipeRegongnizer = UISwipeGestureRecognizer(target: self, action: #selector(self.handleSwipeUp))
    swipeRegongnizer.direction = UISwipeGestureRecognizerDirection.up
    swipeRegongnizer.delegate = self
    tableview.addGestureRecognizer(swipeRegongnizer)
}

func handleSwipeUp(gesture: UISwipeGestureRecognizer) {
        print("swiped up")
}

func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return 100
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = UITableViewCell()
    cell.textLabel?.text = "cell\(indexPath.row)"
    return cell
}
}

Answer 1

1. Implement UIGestureRecognizerDelegate. 2. set delegate.

    yourGesture.delegate = self

3. add the following function in your respective swift file.

func gestureRecognizer(_ gestureRecognizer: UIGestureRecognizer, shouldRecognizeSimultaneouslyWith otherGestureRecognizer: UIGestureRecognizer) -> Bool {
        return true
}
