I am getting this warning multiple times when i goto a view using google maps.This started as soon as i migrated to swift 2.0 and xcode 7 for my exising project .Im using google maps in my project. See the console log below 
I have gone through some links but was not helpful https://code.google.com/p/gmaps-api-issues/issues/detail?id=8459
As indicated in your console log, this is caused by an issue in the Google Maps SDK. The issue has been fixed in the latest Google Maps SDK release, so if you update it, it should work like before.
If you're using CocoaPods, just add pod 'GoogleMaps' in your podfile and run $ pod install.
In my case I needed doing 1) update cocoa pod, 2) setup again, and 3) update pods.
1) $ gem update cocoapods
2) $ pod setup
3) $ pod update
