How to find out distance between coordinates?

Question

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

Answer 1

import UIKit
import CoreLocation

class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        var currentLocation = CLLocation(latitude: 23.1929, longitude: 72.6156)
        var DestinationLocation = CLLocation(latitude: 23.0504, longitude: 72.4991)
        var distance = currentLocation.distance(from: DestinationLocation) / 1000
        print(String(format: "The distance to my buddy is %.01fkm", distance))
    }
}

Answer 2

Swift 5.

func calculateDistance(mobileLocationX:Double,mobileLocationY:Double,DestinationX:Double,DestinationY:Double) -> Double {

        let coordinate₀ = CLLocation(latitude: mobileLocationX, longitude: mobileLocationY)
        let coordinate₁ = CLLocation(latitude: DestinationX, longitude:  DestinationY)

        let distanceInMeters = coordinate₀.distance(from: coordinate₁)

        return distanceInMeters
    }

use to

let distance = calculateDistance("add parameters")

Answer 3

func calculateDistanceInMiles(){

    let coordinate₀ = CLLocation(latitude:34.54545, longitude:56.64646)
    let coordinate₁ = CLLocation(latitude: 28.4646, longitude:76.65464)
    let distanceInMeters = coordinate₀.distance(from: coordinate₁)
    if(distanceInMeters <= 1609)
    {
        let s =   String(format: "%.2f", distanceInMeters)
        self.fantasyDistanceLabel.text = s + " Miles"
    }
    else
    {
        let s =   String(format: "%.2f", distanceInMeters)
        self.fantasyDistanceLabel.text = s + " Miles"

    }
}

Answer 4

import CoreLocation

//My location
let myLocation = CLLocation(latitude: 31.5101892, longitude: 74.3440842)

//My Next Destination
let myNextDestination = CLLocation(latitude: 33.7181584, longitude: 73.071358)

//Finding my distance to my next destination (in km)
let distance = myLocation.distance(from: myNextDestination) / 1000

Answer 5

Swift 4.1

import CoreLocation

//My location
let myLocation = CLLocation(latitude: 59.244696, longitude: 17.813868)

//My buddy's location
let myBuddysLocation = CLLocation(latitude: 59.326354, longitude: 18.072310)

//Measuring my distance to my buddy's (in km)
let distance = myLocation.distance(from: myBuddysLocation) / 1000

//Display the result in km
print(String(format: "The distance to my buddy is %.01fkm", distance))

Answer 6

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
 }
