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 1:

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
 }

Solution 2:

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))

Solution 3:

Try this out:

distanceInMeters = fromLocation.distanceFromLocation(toLocation)
distanceInMiles = distanceInMeters/1609.344

From Apple Documentation:

Return Value: The distance (in meters) between the two locations.

Solution 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
