Is it possible to calculate the distance between 2 close points on iOS using Apple map framework or Google framework? For example, i want to get the distance between this 2 blu point with the highest accuracy possible.
Using google maps or apple maps can i get the 2 coordinate with a lot of digit? how can i calculate the distance in centimeters or millimeters?
Try this -
let coordinate0 = CLLocation(latitude: 5.0, longitude: 5.0)
let coordinate1 = CLLocation(latitude: 5.0, longitude: 3.0)
let distanceInMeters = coordinate0.distance(from: coordinate1)
Yes, you'll get accurate enough position information. CLLocation has a distance(from: CLLocation) function that does the trick and gives accurate results also for short distances.
