simple solution for use inside mapViewDidFinishLoadingMap:

    func mapViewDidFinishLoadingMap(_ mapView: MKMapView) {

        //center of USA, roughly. for example
        let center = CLLocationCoordinate2D(latitude: 38.573936, longitude: -92.603760) 
        let latMeters = CLLocationDistance(10_000_000.00) //left and right pan
        let longMeters = CLLocationDistance(5_000_000.00) //up and down pan
        
        let coordinateRegion = MKCoordinateRegion(
            center: center,
            latitudinalMeters: latMeters,
            longitudinalMeters: longMeters)
        
        let cameraBoundary = MKMapView.CameraBoundary(coordinateRegion: coordinateRegion)
        mapView.setCameraBoundary(cameraBoundary, animated: true)
    }
