Can I get the accuracy of GPS location in iOS?

I've seen Android developers get the accuracy of a GPS location. Is there a way that I can get the accuracy of my currenct GPS location in iOS?

I am using the code from this answer to get my location:

 locationManager = [[CLLocationManager alloc] init];
 locationManager.delegate = self;
 locationManager.distanceFilter = kCLDistanceFilterNone;
 locationManager.desiredAccuracy = kCLLocationAccuracyBest;
 [locationManager startUpdatingLocation];


 - (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation {
     NSLog(@"OldLocation %f %f", oldLocation.coordinate.latitude, oldLocation.coordinate.longitude);
     NSLog(@"NewLocation %f %f", newLocation.coordinate.latitude, newLocation.coordinate.longitude);
 }

Use horizontalAccuracy and verticalAccuracy properties in CLLocation class. If horizontalAccuracy is a huge value you can discard the signals.

Also make sure to check the timeStamp with current date to ensure that the GPS signal is not cached.

horizontalAccuary of CLLocation gives the estimated positional error in meters related to the latitude, longitude coordinate.

verticalAccuracy gives the estimated error related to altitude.

There are 2 properties on the CLLocation -horizontalAccuracy and -verticalAccuracy. Most of times the accuracy is based on the hardware that you are using to get the location
