ios - How to open Google Maps to show route using Swift

Question

I read around the Internet but couldn't find a legit answer. I need to open Google Maps when the user clicks a button to show directions. Start and destination must be automatically filled.

How can I achieve this in Swift?

If anyone has a solution, please provide me with a sample code. The start is always going to be the user's current location.

Answer 1

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://");
        }
    }
