Can I get a store name/restaurant name with mapkit?(swift) - ios

Question

I have a mapview and I added a method to drop a pin on the location where the user had pressed. The callout shows the address of the location as shown on the image.
screenshot of my mapview with annotation pin and callout view.
And my code is as following:
func onTapGestureRecognized(sender: UILongPressGestureRecognizer) {
self.mapView.removeAnnotations(mapView.annotations)
let location = tapRecognizer.location(in: mapView)
let coordinate = mapView.convert(location,toCoordinateFrom: mapView)
let getLat: CLLocationDegrees = coordinate.latitude
let getLon: CLLocationDegrees = coordinate.longitude
let theLocation: CLLocation = CLLocation(latitude: getLat, longitude: getLon)
let geoCoder = CLGeocoder()
geoCoder.reverseGeocodeLocation(theLocation, completionHandler: { (placemarks, error) -> Void in
// Place details
var placeMark: CLPlacemark!
placeMark = placemarks?[0]
var theLocationName = ""
var theStreetNumber = ""
var theStreet = ""
var theCity = ""
var theZip = ""
var theCountry = ""
// Address dictionary
print(placeMark.addressDictionary as Any)
// Location name
if let locationName = placeMark.name{
theLocationName = locationName
}
if let streetNumber = placeMark.subThoroughfare{
theStreetNumber = streetNumber
}
// Street address
if let street = placeMark.thoroughfare {
theStreet = street
}
// City
if let city = placeMark.locality {
theCity = city
}
// Zip code
if let zip = placeMark.postalCode{
theZip = zip
}
// Country
if let country = placeMark.isoCountryCode{
theCountry = country
}
let annotation = MKPointAnnotation()
annotation.title = theLocationName
annotation.subtitle = theStreetNumber + " " + theStreet + ", " + theCity + ", " + theCountry + ", " + theZip
if let location = placeMark.location {
annotation.coordinate = location.coordinate
// Display the annotation
self.mapView.showAnnotations([annotation], animated: true)
}
})
}
As you can see, when I try to get the location name by calling the line (((( if let locationName = placeMark.name )))), I can only get the address: "5197 Yonge St", instead of the restaurant name : " Pho 88 Restaurant ".
Can anyone tell me where I did wrong? or is it simply cannot be achieved? Thanks!

I can't give you a complete answer, but I may be able to point you in the right direction. As far as I can see, you will only ever get a single entry returned for placemarks, but you can get a more complete list using MKLocalSearchRequest. the challenge is going to be how you match up the returned values to exactly which one you want - maybe you have to ask the user to select from a short list? Also, I think you need to specify which type of establishment you're searching for. Here's something you could include within your completion handler above
let request = MKLocalSearchRequest()
request.naturalLanguageQuery = "restaurant" // or whatever you're searching for
request.region = MKCoordinateRegion(center: CLLocationCoordinate2D(latitude: getLat, longitude: getLon), span: self.mapView.region.span)
let search = MKLocalSearch(request: request)
search.start { response, error in
guard let response = response else {
print("There was an error searching for: \(request.naturalLanguageQuery) error: \(error)")
return
}
print("There are \(response.mapItems.count)")
for item in response.mapItems {
// You may be able to match the address to what the geoCode gives you
// or present the user with a list of options
print("\(item.name), \(item.placemark)")
}
}
When I was testing this, the addresses didn't always match up, even when zoomed in - so that geoCoder might give me 1-3 Some Street while the MKLocalSearchRequest returned a restaurant at 3 Some Street
