Maybe the simulator can't retrieve the default CLLocationManager location. You can try this:

- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation
{
    location = newLocation.coordinate;

// Manually setting a default location for simulator only
    if(TARGET_IPHONE_SIMULATOR){
    location.latitude= 45.00;
    location.longitude= 45.00;
    }
}
