Google Maps SDK for iOS crashing on startup using Monotouch bindings
I am trying to test out the new Google SDK for iOS using the GoogleMapsSample on GitHub, however, every time I run the app crashes trying to create an instance of GMSMapView. This is happening when trying to run on both the simulator and the device.
I have enabled the SDK from the developer console and updated the GMSServices.ProvideAPIKey call to use my iOS API key, from what I have read that is pretty much all that's required?
I did notice this bug which was logged against the actual SDK which mentions an issue relating to OpenGL so not sure if that's what the issue is here. However, as I can't get access to a log using the simulator I ran it on the device and checked the log out using XCode and the error does seem to relate to this - stack trace:

Update #2
Google suggested a workaround and it has been implemented. I have successfully deployed to device :) you can find the working solution on MonoTouch-Bindings Repo
Google will fix this on their upcoming release as stated here.
Happy Coding
Update
There is a bug on Google Maps that makes it impossible to use it in Xamarin.iOS, this bug has been reported to google here
http://code.google.com/p/gmaps-api-issues/issues/detail?id=5018
Please Star it so google notices and fixes it faster ;)
I have updated the bindings to version 1.1.0 of Google Maps you can find them here https://github.com/mono/monotouch-bindings/tree/master/GoogleMaps
Please note I have not updated the sample to reflect the Api changes yet.
Hope this helps

CommunityXamarin did not update to the newer version since they did the last update on 14 december. I believe that this crash relates to this issue. Maybe the API keys you can generate today are just build for 1.1.0 and newer.
