geocodeAddressString

I want to read almost a million addresses in foor loop using CLGeocoder and save their coordinates. I have also put a 2 second pause in each loop, but every time I want to run the program in Xcode, after 200 or 300 iterations, the program closes suddenly. Does anyone know the reason? Is there a problem with the code? here is my code : func createCSV(from recArray:[Dictionary]) { var csvString = (Adresse);(latitute );(longitude)nn for dct in recArray { csvString = csvString.appending((String(describing:dct[Adresse]!));(String(describing: dct[latitute]!));(String(describing: dct[longitude]!))n) } let fileManager = FileManager.default do { let path = try fileManager.url(for: .documentDirectory, in: .allDomainsMask, appropriateFor: nil, create: false) let fileURL = path.appendingPathComponent(CSVRec.csv) try csvString.write(to: fileURL, atomically: true, encoding: .utf8) } catch { print(error creating file) } } func getLocation(for address: String) async throws -> CLLocationCoordinate2D { guard let coordinate

Hi,I'm trying to show directions on a MKMapView from a users current location to a desired location chosen by the user. I've got it working to when user selects a location, it will open it in the Apple Maps app. I would like he directions to show on the MapView within my app.The code is below. I'm under time pressure also so an answer would be really great ASAP.import UIKit import MapKit class LocationSearchTable : UITableViewController { var handleMapSearchDelegate:HandleMapSearch! / var matchingItems:[MKMapItem] = [] var mapView: MKMapView! func parseAddress(selectedItem:MKPlacemark) -> String { / let firstSpace = (selectedItem.subThoroughfare != nil && selectedItem.thoroughfare != nil) ? : / let comma = (selectedItem.subThoroughfare != nil || selectedItem.thoroughfare != nil) && (selectedItem.subAdministrativeArea != nil || selectedItem.administrativeArea != nil) ? , : / let secondSpace = (selectedItem.subAdministrativeArea != nil && selectedItem.administrativeArea != nil) ?
