I search places with the MKLocalSearchCompleter and refine the results when the tableView cell is selected. When a MKLocalSearchCompletion is selected and MKLocalSearch.Request() is started, I get these Errors (example selects Los Angeles): 
According to my research this is a very rare problem?!

  • [SearchAttribution] No matching attribution source found for org.volunteermatch ... (+4 other domains)

  • Error loading attribution info for identifier org.volunteermatch from geod: Error Domain=GEOErrorDomain Code=-8 "No matching attribution source found for org.volunteermatch" UserInfo={NSDebugDescription=No matching attribution source found for org.volunteermatch} ... (+4 other domains)

These are the instance variables in a TableViewController:
Code Block 
var searchCompleter = MKLocalSearchCompleter()
var searchResults = [MKLocalSearchCompletion]()

This code is running everytime the search term is changed:
Code Block 
searchCompleter.queryFragment = text
searchCompleter.resultTypes = .address
searchCompleter.region = region

In tableView … didSelectRowAt… this code is executed:
Code Block 
let selectedItem = searchResults[indexPath.row]
        
let searchRequest = MKLocalSearch.Request()
searchRequest.naturalLanguageQuery = selectedItem.title
searchRequest.resultTypes = .address
        
let search = MKLocalSearch(request: searchRequest)
search.start { (response, error) in
            
      guard let coordinate = response?.mapItems[0].placemark.coordinate else {
          return
      }
      // send to mainVC
     self.delegate?.userSelectedPlace(coordinate: coordinate)
}

Can you please check with the latest iOS 15 beta build on a device. Please file a report via Feedback Assistant (https://feedbackassistant.apple.com/), if the issue still persists and include the runnable project that demonstrates the issue. 

As a side note, when executing a local search request based on a result you have received from MKLocalSearchCompleter it is highly recommended that you use MKLocalSearch.Request's initializer that is specifically designed for that purpose: init(completion: MKLocalSearchCompletion) - https://developer.apple.com/documentation/mapkit/mklocalsearch/request/1452301-init

This lets MapKit tie together your search with the exact item the user previously selected, rather than performing a brand new search based on the string.

Encoutering the exact same problem.

Already using MKLocalSearch.Request's init(completion: MKLocalSearchCompletion) but receiving a lot of errors:

E.g. when passing the MKLocalSearchCompletion representing

Lisbon, Lisbon, Portugal @ <+38.72035640,-9.13731930> +/- 0.00m, region CLCircularRegion (identifier:'<+38.73709804,-9.16049930> radius 10213.85', center:<+38.73709804,-9.16049930>, radius:10213.85m)

I see the following errors:

We are seeing the same thing suddenly. Search results are broken with the following errors out of the blue.

I'm having the same issue.

I've noticed that this same exact issue was produced in Apple's own iOS sample project "SearchingForNearbyPointsOfInterest." Unfortunately, this project was recently replaced with a new iOS16 project called "InteractingWithNearbyPointsOfInterest" (https://developer.apple.com/documentation/mapkit/interacting_with_nearby_points_of_interest), so I'm not sure if people can test it anymore. I have not tested this new project yet because I don't have Xcode 14.

These errors are occurring for me only when I query the searchCompleter results, not when I turn the searchCompletion into an MKLocalSearch. So Frameworks Engineer's suggestion is not particularly helpful in this case.
