geocodeAddressString

It's still not working in Beta 5. I've tried geocodeAddressString and geocodeAddressDictionary. If their completionHandlers return at all, the placemarks array will be nil.

Hi thereHere is the complete View Controller page - which compilles in Swift 2import UIKit import MapKit import CoreLocation class ViewController: UIViewController { @IBOutlet weak var sourceField: UITextField! @IBOutlet weak var destinationField1: UITextField! @IBOutlet weak var destinationField2: UITextField! @IBOutlet weak var topMarginConstraint: NSLayoutConstraint! @IBOutlet var enterButtonArray: [UIButton]! var originalTopMargin: CGFloat! let locationManager = CLLocationManager() var locationTuples: [(textField: UITextField!, mapItem: MKMapItem?)]! var locationsArray: [(textField: UITextField!, mapItem: MKMapItem?)] { var filtered = locationTuples.filter({ $0.mapItem != nil }) filtered += [filtered.first!] return filtered } override func viewDidLoad() { super.viewDidLoad() originalTopMargin = topMarginConstraint.constant locationTuples = [(sourceField, nil), (destinationField1, nil), (destinationField2, nil)] locationManager.delegate = self locationManager.requestWhenInUseAuthorization() if CLLocationMa

As already explained, `geocodeAddressString` and its closure will be called asynchronously.This sort of thing may happen even in C, when you pass callback to some asynchronous call.If you want to execute the callback closure strictly in order, you may need to start the next aync call after the current is finished.That can be a little bit tricky (for person who are not accustomed to it) and take more time to finish all, so please consider if you really need it.If you just want to do something after all async calls are finished, you can use DispatchGroup. let group = DispatchGroup() //<- for loc in arrayOfStrings ?? [] { print(Geocoder call:, loc) let geocoder = CLGeocoder() group.enter() //Call `enter()` before invoking each async call geocoder.geocodeAddressString(loc) { placemarks, error in //All UI manipulation should be done in the main thread. DispatchQueue.main.async { if let placemark = placemarks?.first, let location = placemark.location { let mark = MKPlacemark(placemark: placemark) if !fi

The code is not executing serially because it involves completion handlers, which are inherently asynchronous . Your getLocation function only starts an asynchronous operation, but does not wait for it to finish. Your queue.sync calls here don't achieve anything here, because the calls to getLocation are already synchronous (only the completion handlers are executed asynchronously). So, you've effectively written: self.getLocation(from: self.sourceString) { … } self.getLocation(from: self.destinationString) { … } // I think you meant destination, not source here! if(/*some test*/) { /* some stuff */ } These things run in order, but the parts represented by { … } are completion handlers that run later — which is to say, after your if statement. If you want to get the destination location only after you have the source location, and test the coordinates after you have both locations, you'd need something like this: self.getLocation(from: self.sourceString) { … self.getLocation(from: self.destinationString) { …

The WeatherKit API only needs you to provide a CLLocation object, nothing about the name of a city/country. You will have to use your own list of city/country names and get the locations of these to pass to WeatherKit. Helpfully, CLGeocoder has that functionality already. Here is an example of how to use it: func location(for address: String) async throws -> CLLocation? { let placemarks = try await CLGeocoder().geocodeAddressString(address) return placemarks.first?.location } if let londonLocation = try? await location(for: London) { // pass londonLocation to WeatherKit let coordinates = londonLocation.coordinate print(coordinates) // CLLocationCoordinate2D(latitude: 51.5033466, longitude: -0.0793965) }

Same issue here. Had to switch to the geocodeAddressString function of CLGeocoder and pass the postal code directly to restore functionality.

Is it really how yoiu use it ? how i use it : getLat(withAddress: address1) { (result) in lat1 = result } Or is it getLatFromAddress(withAddress: address1) { (result) in lat1 = result } geocodeAddressString is async by nature, AFAIK you cannot change it. https://mhorga.org/2015/09/23/completion-handlers-in-ios.html So the ways to solve it: do as you have written: do the print (or any other code) in the completion handler. or use async wait pattern (declaring your func async)
