Glitchy UIRefreschControl animation with large headings for the navigation bar

Question

I have a controller built into a navigation controller with large headers and a UIRefreshControl. When I click on an update in my TableView, the activity indicator animation is very buggy.

I don’t know if I have bad behavior in my code?

tableView.refreshControl = UIRefreshControl() tableView.refreshControl?.addTarget(self, action: #selector(downloadData), for: .valueChanged)

Answer 1

navigationController?.navigationBar.isTranslucent = true
