Summary: MKMapView leaks memory when dismissed from visible view (or UICollectionViewCell, UITableViewCell, etc.) Steps to Reproduce: 1. Add MKMapView to UIView as a subview. 2. Present view on screen. 3. Dismiss view from screen. 4. Memory allocated by MKMapView is not being reclaimed. Expected Results: MKMapView allocated memory should be freed. Actual Results: Only ~20% of memory allocated by MKMapView after it was shown is reclaimed. Version: 11.0 (15A5318g) Notes: Calling following from deinit of owner helps to reclaim almost all of memory MKMapView allocated. ``` func applyMapViewMemoryLeakFix() { switch mapView.mapType { case .standard, .mutedStandard: mapView.mapType = .satellite default: mapView.mapType = .standard } mapView.showsUserLocation = false mapView.delegate = nil mapView.removeFromSuperview() mapView = nil } ```
