UIRefreshControl beginRefreshing() shows activity indicator, but it is not animating

Question

I use this code to beginRefreshing for the first time i visit my UIViewController

var refreshControl = UIRefreshControl()
refreshControl.addTarget(self, action: #selector(self.loadPlayer), for: .valueChanged)

self.playersTable.addSubview(refreshControl) 
self.refreshControl.beginRefreshing()
self.loadPlayer()

function loadPlayer is called and the spinner is shown, but the problem is the spinner does not animating at all, and it looks bad. Any solution to trigger RefreshControl valueChanged?

I have tried another code like this but didn`t work

self.refreshControl.layoutIfNeeded()
self.refreshControl.beginRefreshing()
self.playersTable.setContentOffset(CGPoint(x: 0, y: -self.refreshControl.frame.size.height), animated: true)

i know i could use UIActivityIndicatorView and only show it for the first time, but could i use only UIRefreshControl for efficiency ?

Had the exact same problem - what worked for me is to put the self.refreshControl.beginRefreshing() inside viewWillAppear -

- (void)viewWillAppear:(BOOL)animated { [super viewWillAppear:animated]; [self.refreshController beginRefreshing]; }
