UIRefreshControl - beginRefreshing not working when UITableViewController is inside UINavigationController

Question

I\'ve setup a UIRefreshControl in my UITableViewController (which is inside a UINavigationController) and it works as expected (i.e. pull down fires the correct event). Howe

Here is Swift 3 and later extension that shows spinner as well as animate it.

import UIKit
extension UIRefreshControl {

func beginRefreshingWithAnimation() {

    DispatchQueue.main.asyncAfter(deadline: .now() + 0.05) {

        if let scrollView = self.superview as? UIScrollView {
            scrollView.setContentOffset(CGPoint(x: 0, y: scrollView.contentOffset.y - self.frame.height), animated: true)
          }
        self.beginRefreshing()
      }
   }
}
