this one helps. I found I was able to solve this problem by adding the map creation to ViewWillAppear as opposed to having it in the ViewDidLoad.

code :

 override func viewWillAppear(_ animated: Bool) {
    let ud = UserDefaults.standard
    let startingX = ud.double(forKey: "startingX")
    let startingY = ud.double(forKey: "startingY")

    let camera = GMSCameraPosition.camera(withLatitude: startingX, longitude: startingY, zoom: 18.0)
    googleMapView.camera = camera

    self.googleMapView.mapType = .hybrid

    self.googleMapView.settings.scrollGestures = true
    self.googleMapView.settings.rotateGestures = true
    self.googleMapView.settings.consumesGesturesInView = true
}

Align the camera to make screen space origin at the bottom-left corner

Does that help In a 2D game, you have an X-axis and Y-axis. When increasing an object's X-value, you could say the object is going right. When increasing the Y-value, you could say the object is going up.
In a 3D game, there is another additional axis, the Z-axis. This makes it possible to gain 'depth' in games.

To fix the issue you can do Excellent question, I created a method to return a Vector3 which is relative to the screen position. I'm not sure if there is a built in way to do this or easier way but here is my code below. Good luck on your program me.

code :

public Vector3 relativeVector(float x, float y,OrthographicCamera c){
    return new Vector3(x+c.position.x-c.viewportWidth/2,y+c.position.y-c.viewportHeight/2,0);
}

seems to work fine In viewDidLoad I give my current Location to show in Map. , Finally I tried something using GMSCameraPosition fix the problem.

code :

-(void)textFieldDidEndEditing:(UITextField *)textField{

if(textField==self.txtAddress  && self.txtAddress.text.length > 0)
{  
    [CATransaction begin];
    [CATransaction setValue:[NSNumber numberWithFloat:2.0] forKey:kCATransactionAnimationDuration];
    GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude: [strForLatitude doubleValue]
                                                            longitude: [strForLongitude doubleValue] zoom: 14];
    [mapView_ animateToCameraPosition: camera];
    [CATransaction commit];
    self.ImageMarkerMapCentre.hidden = NO;
}

if(textField==self.txtDropoffAddress  && self.txtDropoffAddress.text.length > 0)
{
    [CATransaction begin];
    [CATransaction setValue:[NSNumber numberWithFloat:2.0] forKey:kCATransactionAnimationDuration];
    GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:[[pref objectForKey:@"Destination_Latitude"] doubleValue] longitude:[[pref objectForKey:@"Destination_Longitude"] doubleValue] zoom:14];
    [mapView_ animateToCameraPosition: camera];
    [CATransaction commit];
    self.ImageMarkerMapCentre.hidden = YES;

CSS transform: rotate top-left corner of child over bottom-left corner of parent

Any of those help Is there a way how to automatically achieve this without the knowledge of line height/parent height with negative translate? , You can try this:

code :

.parent {
  border: 1px solid green;
  border-left-color: red;
  margin-top:100px;
  position:absolute;
}

.child {
  border: 1px solid orange;
  border-left-color: red;
  transform: rotate(-90deg) translateY(100%);
  transform-origin: bottom left;
}

<div class="parent">
  <div class="child">
    CONCEPT
  </div>
</div>

Why is origin usually top left corner in painting APIs when logically and native GL is at bottom left corner?

I hope this helps you . 2D raster drawing having a top-left origin, with rightward x-axis and downward y-axis, is most likely mirroring the CRT scanning pattern. A frame buffer organized in this way -- with row-major pixels from top to bottom -- can be fed in linear order to the RAMDAC producing the signal for the CRT. Other organizations would require the graphics system to perform more arithmetic, for no practical benefit.
