I am trying to build a compass app on iOS. I have looked around the web, but I am pretty confused which would be the best way.

Right now I am using CoreLocation

func locationManager(_ manager: CLLocationManager, didUpdateHeading newHeading: CLHeading)
{
    trueHeading.text = String(newHeading.trueHeading)
    magneticHeading.text = String(newHeading.magneticHeading)
}

But I compared with the compass app on the iPhone and it shows different values sometimes.

Is there a better way to find TRUE north? Using CoreMotion or something like that?

After some digging I found this answer http://stackoverflow.com/a/15470571/4915700 . Contains a lot of info and I believe I will stick to using CLHeading – razvan Sep 30 '16 at 08:40
