How to find out distance between coordinates?

I want to make it so that it will show the amount of distance between two CLLocation coordinates. Is there someway to do this without a complex math formula? If there isn't how would you do it with a formula?

Solution

  • CLLocation has a distanceFromLocation method so given two CLLocations:

    CLLocationDistance distanceInMeters = [location1 distanceFromLocation:location2];

    or in Swift 4:

    //: Playground - noun: a place where people can play

import CoreLocation


let coordinate₀ = CLLocation(latitude: 5.0, longitude: 5.0)
let coordinate₁ = CLLocation(latitude: 5.0, longitude: 3.0)

let distanceInMeters = coordinate₀.distance(from: coordinate₁) // result is in meters

    you get here distance in meter so 1 miles = 1609 meter

    if(distanceInMeters <= 1609)
 {
 // under 1 mile
 }
 else
{
 // out of 1 mile
 }
