How to update Google Maps marker position in swift/iOS

Answer 1

You can try the online swift to objective c converters. Like
http://objc2swift.me
These converts are used to convert objective c to Swift. I know you want to convert Swift to objective C. But I think you can learn some think to here. Just write the code. Swift is very similar to objective c.Only difference in syntax. You can understand very easily.

Answer 2

Here is the code, Create a button, add selector to that button. Hope you will set your google map.
NSMutableData *webData;
#property NSURLConnection *connection;
-(void) getResult //call this in button selector
{
marker=nil; //create a GMSMarker globally.
