LabelMarker | small tools for marking training set label | Machine Learning library

• UIViewController sets self.view as GMSMapView in viewDidLload
• A method will create markers and store them in self.markers and set marker.map to the self.view as! GMSMapView

So far the app behaves well

• Later, another method after some action (looking to toggle those markers) sets all self.markers.map to nil

Up to here all goes well and the markers are gone from the map

• Again, another method that wants those markers back, sets all self.markers.map = self.view as! GMSMapView

Here the cpu gets stuck at 100% (on a simulator in an 8 core machine)

If the self.markers.map gets reset to nil again, the cpu goes back to ~0% and all is good.

Is this a limitation on cpu or GoogleMaps SDK? Is there a way to avoid the problem?

After extracting the bits of code related, I added also similar conditions where a Label is being created as an icon for another marker.

After some tests it seems it is related on the amount of markers to process only. See LabelCount and set to different values, in my cpu the problem appeared with 200 but not with 100 markers (ie: 400 markers as there is an extra marker for the label)
