I know it\'s possible to start the iPhone maps application by calling openURL on a google maps URL with parameters saddr and daddr wit
openURL
saddr
daddr
If you don't provide source location, it will take current location as source. Try below code-
let urlString = "http://maps.apple.com/maps?daddr=(destinationLocation.latitude),(destinationLocation.longitude)&dirflg=d" }
UIApplication.shared.openURL(URL(string: urlString)!)
