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.

I'm having this same error 159, but I actually do already have a team provisioning profile and that's not solving the issue. How can we get around this error?

Nevermind, I found the solution. You have to go your App's Target > Signing and Capabilities, then add the "Family Controls" capability (even if you're just using family controls for an individual). This will add the necessary entitlement to your entitlements file, and your problems are solved.
