How to open maps App programmatically with coordinates in swift?

Question

I have latitude and longitude that I want to open into my map application. I tried this code from HERE.

    func goToMap(){

    var lat1 : NSString = self.v         


        

Answer 1

If what you want is something simple without importing any framework you can just create a URL: https://maps.apple.com/?ll=\(latitude),\(longitude)

Is similar to @saniel-saidi response but this one opens just the map with location sent, not the navigation thing

Answer 2

The MKMapItem approach above works great if you want granular control over the information that is displayed in Maps.

Otherwise, the code below works great as well, :

// Open and show coordinate
let url = "http://maps.apple.com/maps?saddr=\(coord.latitude),\(coord.longitude)"
UIApplication.shared.openURL(URL(string:url)!)

// Navigate from one coordinate to another
let url = "http://maps.apple.com/maps?saddr=\(from.latitude),\(from.longitude)&daddr=\(to.latitude),\(to.longitude)"
UIApplication.shared.openURL(URL(string:url)!)

However, the code above does not let you to send in a custom name of the place. Instead, it will show the address.

The code above also lets you navigate from any source coordinate, which I don't know if you can do with the MKMapItem approach.

This works as a charm for me

let coordinate = CLLocationCoordinate2DMake(theLatitude, theLongitude)
let region = MKCoordinateRegionMake(coordinate, MKCoordinateSpanMake(0.01, 0.02))
let placemark = MKPlacemark(coordinate: coordinate, addressDictionary: nil)
let mapItem = MKMapItem(placemark: placemark)
let options = [
    MKLaunchOptionsMapCenterKey: NSValue(mkCoordinate: region.center),
    MKLaunchOptionsMapSpanKey: NSValue(mkCoordinateSpan: region.span)]
mapItem.name = theLocationName
mapItem.openInMaps(launchOptions: options)
