I also have this problem, or one similar. let circleDiameterMeters = 3000000.0 let nspot = CLLocationCoordinate2D(latitude: 82.75752195981894, longitude: -33.25326661642988) // Northern Greenland let newCircle = MKCircle.init(center:nspot, radius:MaxCircleDiameterMeters/2) self.mapView.addOverlay(newCircle) This code created this MKCircle, 1,500km radius, centered in Greenland. The view from the Arctic looks like: The view from the Antarctic looks like: You can see the strangeness in the rendering of this MKCircle, which instead of a circle, seems to be the top of the circle bending in on itself, proceeding through the center of the Earth, and coming out the other end.
