Got a SIGABRT while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries
used by your application.
=================================================================
I tried to wrap the code in try catch but still experiencing crashes. Any idea what might be the issue?
I found the solution in case someone else faces the same issue .You will need to add [Privacy -Microphone Usage Description] property to the info.list with a text description so that the app will ask you to allow access to use the microphone .

I received a crash in iOS12.
The way to reproduce:
1.Play a video with UIWebView, then the video will play in fullScreen.
2.After the video start play, tap the left-top reduced Button to stop the video.
3.Replay it and the video will still in fullScreeen.
4.Repeat step2 and step3 several times.
5.Normal speed, at most 10 times, the crash will come.
Some detail info of the crash:

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
Our Xamarin-based iOS app works fine on iPhone but crashes on iPad. The offending call is to SetEnableIO:
audioUnit = new AudioUnit.AudioUnit(component);
audioUnit.SetEnableIO(true, AudioUnitScopeType.Input, kInputBus);

Got a SIGABRT while executing native code. This usually
indicates a fatal error in the mono runtime or one of the
native libraries used by your application.
Does anyone know How to get around this problem? Regards.
Environment:
Visual Studio 2015 with update 3
Xamarin 4.2.0.680
Xamarin.iOS 10.0.0.6
iPad is running iOS 10.0.1
We finally nailed the problem down. Apparently, Xamarin has not yet been fully tested on iOS 10. The OS has introduced some new privacy settings. If you do not define the settings that your iOS app intends to use, you will see your app crash with SIGABRT errors. The privacy settings can be defined in Info.plist. In our case, it was NSMicrophoneUsageDescription. Hope you find this useful.
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.
I get a very infrequent crash when stopping MKMapView location services in the applicationDidEnterBackground method. (I'm doing this to ensure that my app does not use location services when the app is in the background.)
The code which gives rise to the crash looks like this:
- (void)MyAppDelegate applicationDidEnterBackground:(UIApplication *app) {
[self.baseAppViewController stopUserTracking];
}
The stopUserTracking method does the following:
-(void)stopUserTracking {
[baseAppViewController.mapView setUserTrackingMode:MKUserTrackingModeNone];
[baseAppViewController.mapView setShowsUserLocation:NO];
}
Note that the baseAppViewController is never released by the app; neither is the mapView. The baseAppViewController is the delegate of its mapView. The delegate is never set to nil.
Here is the stack trace, which ends with a call to MKNormalizedPointForLayer. I've read elsewhere that the MKNormalizedPointForLayer may be due to an invalid annotation latlng (http://stackoverflow.com/questions/9766272/error-in-main-thread-mknormalizedpointforlayer). However I doubt that this is the case for my app: I've tried purposefully adding annotations with invalid lat/lngs, and don't get this error. The fact that this is happening as a result of the MKTilesRequireGoogleLegalNotices call is intriguing, but completely puzzling. Any thoughts?

I am not 100% sure that it can be that, but your problem might come from a "delegate" problem.
Try to call this line in your method stopUserTracking :
baseAppViewController.mapView.delegate = nil;
This should prevent the map from sending information to deallocated instance of your view controller, causing your app to crash.
Be sure to add this line when your app is reloading from background (maybe in viewWillAppear ?) to make sure your app behaves correctly :
baseAppViewController.mapView.delegate = self;
If it does not solve your problem, try to enable "Zombie object" in the options of your configurations as mentioned here : How do I set up NSZombieEnabled in Xcode 4? it oftens helps to understand what's happening when such unexpected errors happens in apps.
