Use bellow code for both google and apple maps in Swift 3 -

if UIApplication.shared.canOpenURL(URL(string: "comgooglemaps://")!)
        {
            let urlString = "http://maps.google.com/?daddr=\(destinationLocation.latitude),\(destinationLocation.longitude)&directionsmode=driving"

            // use bellow line for specific source location

            //let urlString = "http://maps.google.com/?saddr=\(sourceLocation.latitude),\(sourceLocation.longitude)&daddr=\(destinationLocation.latitude),\(destinationLocation.longitude)&directionsmode=driving"

            UIApplication.shared.openURL(URL(string: urlString)!)
        }
        else
        {
            //let urlString = "http://maps.apple.com/maps?saddr=\(sourceLocation.latitude),\(sourceLocation.longitude)&daddr=\(destinationLocation.latitude),\(destinationLocation.longitude)&dirflg=d"
            let urlString = "http://maps.apple.com/maps?daddr=\(destinationLocation.latitude),\(destinationLocation.longitude)&dirflg=d"

            UIApplication.shared.openURL(URL(string: urlString)!)
        }
