MonoTouch RedLaser SDK Object - xamarin.ios

I am trying to use the RedLaser SDK 3.30 with MonoTouch. Here is the code I am using:
https://github.com/mono/monotouch-bindings/tree/master/RedLaser
When I click the thunderbolt button to scan a barcode, my app crashes on my iPod touch. I am using ARM7. Here is my crash log:

Crash in MetalContext with Xamarin

We have a crash in MetalContext with over 3000 crashes in a single day on iOS 10 devices only. We are unable to track down the root of the error and google reveals nobody else have the same issue. Is there anyone who has any clues to where we can begin to look?

My app kept crashing with the same log, what fixed for me was a quick reset of device, i traced it to webView usage. I cant reset device every time so further testing revealed that i was using xcode 7.3 to build for ios10 that was the problem, after updating to xcode 8 and rebuilding the app i no longer get this crash. Hope this helps

WebKitLegacy - [_WebSafeForwarder forwardInvocation:] application crash in iOS10.0.1

I am getting the following crash only in iOS10.0.1. Its not giving me enough stack trace information. The only clue I have is , seems to be happening from WebView.Because it says "WebKitLegacy - [_WebSafeForwarder forwardInvocation:] ".
The crash log is given below. I have another crash group related to "updateSubviewsOfScrollContentViews" seems like all are related.
Any suggestions on this very helpful. Like how to debug this issue ? Where might be the problem?

While I see the problem originates from IB (An item that references the first attribute must have multiple baselines), I have no clue what to try and change in my storyboard file, which is rather big.
Anyone had the same fate? Any ideas?
I may suggest to open your storyboard file as source
and remove baseline constraints from scenes
You may remove it one by one to localize error reason
In my case the issue was that I had some contraints that were conflicting. I opened Main.storyboard with a text editor and removed the contraints tags from a couple of views and it let me open the file without crashing.

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
Alex
Xamarin 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.
