The Haversine forumula will give you distance and bearing between two points.  
I think you can use the bearing to get your desired info.

MKMapView userLocation heading & a dropped pin

2017-06-23 Thread Eric E. Dolecki 
Happy Friday everyone.

I have a map and on it a userLocation which is tracked. I also have a
dropped pin on the map.

I am trying to determine whether or not the pin is in front, left, right,
or behind the user. I am going to perform calculations within

func locationManager(_ manager: CLLocationManager, didUpdateLocations
locations: [CLLocation]) {

I already determine distance. How might I go about doing this?

Thanks,
Eric
