I\'m trying to display the user\'s current location on a google map but in the case below, the map doesn\'t even get displayed. What should I change to fix this?
The problem is that you are setting the mapView's frame to CGRectZero. This causes the map to have zero height and zero width, no wonder it does not show!
Try setting it to CGRectMake(0,0,200,200) for example, this will give you a map at the left top of the screen with a size of 200 x 200.
I have never used Swift before, so the syntax might be a little different for CGRectMake()
