I'm building a a simple application that allows a user to save their location for later.
The Goal: A user pins their address when at a business, and we save the name of the business
My approach: I'm requesting the location from a locationManager. Then I reverse geocode the CLLocation into a CLPlacemark. Since the placemark isn't recognizing the business name, I start a MKLocalSearch for "restaurants nearby". The response.mapItems are returning locations in completely different cities.
I have specified the region and verified that the placemark is correctly returning the user's address. So, I believe the issue lays within the MKLocalSearch.
Why does it return results for different cities?
