How to open Google Maps to show route using Swift

OK I found the answer myself.

If you want to show directions from the user’s current location, leave the field saddr blank and in the field daddr you can enter the destination coordinates.

This is how I did it

if (UIApplication.sharedApplication().canOpenURL(NSURL(string:"comgooglemaps://")!)) {
            UIApplication.sharedApplication().openURL(NSURL(string:
                "comgooglemaps://?saddr=&daddr=\(place.latitude),\(place.longitude)&directionsmode=driving")!)

        } else {
            NSLog("Can't use comgooglemaps://");
        }
    }
