Adding & Removing A View Overlay in Swift

Question

Following from this question: Loading Screen from any Class in Swift

Issue: The loading overlay view will display but will not hide when hideOverlay

Answer 1

Swift 2

Are you calling hideOverlayView() from a background thread? If you are, you should make sure it runs on the main thread:

dispatch_async(dispatch_get_main_queue(), { // This makes the code run on the main thread
  LoadingOverlay.shared.hideOverlayView()          
})

Swift 3+

DispatchQueue.main.async {
  LoadingOverlay.shared.hideOverlayView()
}
