You should be able to use func reverseGeocodeLocation(_ location: CLLocation!, completionHandler completionHandler: CLGeocodeCompletionHandler!).

MKPointAnnotation has a coordinate property which is a CLLocationCoordinate2D. Convert .coordinate to a CLLocation.

var location = CLLocation.init( annot.coordinate.latitude, annot.coordinate.longitude)

Then you can call reverseGeocodeLocation. Note that this is an asynchronous method so you if you try and use the result in code outside of the CompletionHandler it will most likely fail until the ansynch request returns.

What CompletionHandler will receive is an array of CLPlaceMarks which has the locality property which is the city.

I am told that CLLocationCoordinate2D cannot be converted to CLLocation. Any ideas?
